(Summary) The docking-free design of the Japanese Hinotori surgical robotic system allows the robotic arm to avoid trocar grasping, thereby minimising excessive abdominal wall stress. The aim of this study was to evaluate the safety and efficacy of robotic-assisted radical prostatectomy (RARP) using the Hinotori system and to explore the potential contribution of its docking-free design to postoperative pain reduction. This study reviewed the clinical records of 94 patients who underwent RARP: 48 patients in the Hinotori group and 46 in the da Vinci Xi group. Hinotori group had significantly longer operative and console times (p = 0.030 and p = 0.029, respectively). Perioperative complications and oncologic outcomes did not differ between the two groups. On postoperative day 4, the rate of decline from the maximum visual analogue scale score was marginally significant in the Hinotori group (p = 0.062). The docking-free design may contribute to reducing postoperative pain.

(Summary) This study was performed to evaluate the differences in the perioperative results, renal function, and incidence of hydronephrosis over time between the use of Bricker anastomosis and Wallace anastomosis for robot-assisted intracorporeal ileal conduit urinary diversion (RICIC). Fifty-five patients who underwent RICIC at two institutions were evaluated (Bricker, n = 23; Wallace, n = 32). We investigated changes in estimated glomerular filtration rate and hydronephrosis before surgery and at 3, 6, and 12 months after surgery. The patients in the Bricker group were significantly older than those in the Wallace group. The urinary diversion time was significantly longer in the Bricker group. No significant difference in postoperative renal function was observed. Additionally, no significant difference was observed in the incidence of postoperative hydronephrosis. However, the incidence of right hydronephrosis tended to be high overall, especially in the Wallace group. No patients in either group required repair surgery or ureteral stent placement. In patients undergoing RICIC, there was no difference in postoperative renal function or the incidence of hydronephrosis between Wallace and Bricker anastomosis. Symptomatic hydronephrosis was not observed in either group. The present study showed that each method was equally effective and safe.

(Summary) This study was performed to clarify the therapeutic and diagnostic roles of lymph node dissection (LND) by examining the impact of LND and lymph node yield (LNY) on oncological outcomes in patients undergoing robot-assisted radical cystectomy (RARC). Between 2014 and 2021, 216 patients underwent LND during RARC at Tokushima University Hospital and affiliated hospitals. Among the 216 patients, we compared 115 patients with an LNY of ≥ 20 and 101 with an LNY of < 20 to investigate the impact of LNY on surgical and oncological outcomes. Furthermore, we investigated the impact of LNY and the extent of LND on oncological outcomes by dividing the extent of LND into two groups (standard and extended). The 3-year rates of overall survival (OS) (p = 0.256), cancer-specific survival (CSS) (p = 0.791), and recurrence-free survival (RFS) (p = 0.953) did not differ between the two groups divided by the LNY. A higher LNY was associated with a significantly higher lymph node positivity rate (p = 0.020). The incidence of LND-related major complications was not significantly different between the two groups (p = 0.910). The 3-year survival rates did not differ between the two groups divided by the extent of LND: OS (p = 0.366), CSS (p = 0.814), and RFS (p = 0.689). The LNY and extent of LND were not associated with oncological outcomes in patients undergoing LND during RARC, whereas a higher LNY was associated with lymph node positivity. In the era of adjuvant therapy with immune checkpoint inhibitors, LND during RARC has an important diagnostic role in the detection of pathological node positivity.

(Summary) Robot-assisted surgery (RAS) cannot be achieved without the performance of laparoscopic surgical techniques by a patient-side surgeon (PSS). In many medical institutions in Japan, young urologists often take on the role of a PSS. Participating in RAS as a PSS provides a good opportunity to acquire not only the knowledge necessary for surgery, but also skills in laparoscopic surgical techniques. Learning laparoscopic surgery as a PSS may contribute to improving the quality of RAS. Furthermore, it will lead to skill improvement as an operator in laparoscopic surgery. However, notably, opportunities for young urologists to perform laparoscopic surgery are decreasing in the current era of RAS. Under these circumstances, we believe that cadaver surgical training will become increasingly important in the future. We believe that performance of cadaver surgical training will contribute to increased motivation, enhance the understanding of surgical procedures, and facilitate the acquisition of surgical techniques.

(Summary) Japanese men receiving apalutamide often experience skin-adverse events (AEs), possibly requiring treatment interruption or dose reduction. However, concerns have arisen regarding the impact of these adjustments on the efficacy of apalutamide. Our study evaluated the efficacy, safety, and persistence of apalutamide in men with metastatic castration-sensitive prostate cancer (mCSPC). We retrospectively reviewed the medical records of 108 men with mCSPC from 14 Japanese institutions. The primary outcomes were the efficacy of apalutamide: prostate-specific antigen (PSA) response (50%, 90% and < 0.2 decline) and progression to castration-resistant prostate cancer (CRPC). The secondary outcomes were the skin-AE and compliance of apalutamide. PSA50%, PSA90% and PSA < 0.2 declines were observed in 89.8, 84.3 and 65.7%, and the median time to CRPC progression was not reached. PSA < 0.2 decline and an initial full dose of apalutamide were significantly associated with a longer time to CRPC. The most common AE was skin-AE (50.9%), and there was no association between the occurrence of skin-AE and the time to CRPC (P = 0.72). The median apalutamide persistence was 29 months, which was longer in the initial full dose recipients than in the reduced dose recipients. The dosage is reduced in about 60% of patients within the first year of treatment in the initial full dose recipients. Our findings indicate the effectiveness of apalutamide in Japanese men with mCSPC, despite a substantial portion requiring dose reduction within a year among the initial full dose recipients.

(Summary) Positive core ratios observed on prostate biopsy correlated with higher recurrence rates after LDR-BT. This indicates that the proportion of positive cores in the biopsy may be an important factor in predicting the likelihood of recurrence, especially for patients with GG3 PCa.

(Summary) This study was performed to evaluate the safety and efficacy of lymph node dissection (LND) during robot-assisted radical cystectomy (RARC) compared with open radical cystectomy (ORC). From October 2003 to December 2021, 122 patients underwent LND during RARC and 103 patients underwent LND during ORC at Tokushima University Hospital and Tokushima Prefectural Central Hospital. We investigated the safety and efficacy of LND during RARC by comparing the surgical and oncological outcomes between the two groups. The patients were significantly older in the RARC than the ORC group. The operative time was significantly shorter and the estimated blood loss was significantly lower in the RARC than the ORC group. Although the lymph node yield was significantly higher in the RARC than the ORC group, there was no significant difference in lymph node positivity between the groups. There was no significant difference in the incidence of local recurrence or distant metastasis between the two groups. The 5-year survival rates (overall survival, cancer-specific survival, and recurrence-free survival) were not different between the RARC and ORC groups. This study suggests that the surgical and oncological safety and efficacy of LND during RARC are greater than those of LND during ORC. We believe that LND during RARC is a higher-quality procedure than LND during ORC.

(Summary) The aim of the present study was to identify factors related to the success of trial without catheter (TWOC) in patients with stroke and to examine the effect of the timing of urinary catheter removal on the course of stroke. Patients who were admitted to the Stroke Care Unit of our institution between March 2018 and October 2021 were included. To identify factors related to success of TWOC, a multivariate analysis was performed on the patient's condition at admission and catheter indwelling time. The patients were divided into two groups by the timing of catheter removal, and we assessed the relationship between the timing of catheter removal successful TWOC and recovery of physical function. A total of 118 patients were included. The presence of comorbidities and scores of severity and function at admission were not predictors of successful voiding. The time to achieve voiding sussess was significantly shorter in the early catheter removal group than in the later group (p<0.005). Interestingly, the early group also showed better improvements in physical function. Early removal of catheters may lead to early recovery of bladder function, improvement of physical function, and lower risk of complications in patients with stroke. J. Med.

(Summary) To identify and raise awareness of the radiation exposure of urologists due to X-ray fluoroscopic procedures in daily practice. This was a single-center, cohort study of 30 consecutive patients who underwent periodic percutaneous or transurethral replacements of urinary tract catheters. A total of 55 replacements every 3 months with cases aligned were performed by a single urologist. The urologist's radiation exposure and the incident dose to patients per case were measured with thermoluminescent dosimeters. In the latter 3-month period, the pulse fluoroscopy condition was changed from 15 to 7.5 pulses per second, and collimation was added to the field of view. In the analysis of all patients, the use of a modified pulse rate and collimation did not affect the fluoroscopy time, but it did significantly reduce the air kerma and dose area product; in addition, with respect to the medical exposure dose during percutaneous catheter replacement, fluoroscopy time was longer, but air kerma and dose area product showed significant decreases. As with decreases in medical exposure of patients, the equivalent dose for eye lenses of the urologist decreased from 1.2 mSv in the first 3-month period to 0.2 mSv in the second 3-month period. Similarly, the exposure dose for the extremities also decreased significantly, from 33.9 mSv to 8.1 mSv. Urologists are exposed to non-negligible amounts of radiation due to fluoroscopy. Appropriate management such as modified pulse fluoroscopy condition and precautions are required.

(Summary) Vaginal reconstruction using the posterior vaginal wall is required following radical cystectomy in women with resection of the uterus, adnexa, and anterior vaginal wall. Roll closure and clamshell closure are two widely known techniques. Of these, clamshell closure is recommended because roll closure has a high likelihood of breakdown or a resultant canal that is too narrow for sexual intercourse. In clamshell closure, however, folding the posterior vaginal wall anteriorly can be difficult. Therefore, we devised Mercedes-Benz closure, in which the vaginal wall is sutured from three directions to form a Mercedes-Benz shape, for anastomosis without tension on the vaginal wall. The present study was performed to investigate the efficacy of this alternative surgical technique for vaginal reconstruction. Twenty-six patients who underwent vaginal reconstruction following robot-assisted radical cystectomy were divided into two groups: 15 underwent clamshell closure and 11 underwent Mercedes-Benz closure. The patients' characteristics and surgical outcomes were compared between the two groups. There were no significant differences in clinical characteristics, including age, body mass index, and prior abdominal surgery between the two groups. The median vaginal reconstruction time tended to be longer in the Mercedes-Benz closure group than in the clamshell closure group (35.0 vs. 27.0 min, p = 0.102). No complications associated with vaginal reconstruction were identified. The surgical outcomes were comparable between Mercedes-Benz closure and clamshell closure. If vaginal reconstruction with clamshell closure is difficult, Mercedes-Benz closure is a valuable alternative technique.

(Summary) We report a case of papillary renal cell carcinoma that responded well to the combination of ipilimumab and nivolumab. The patient was a 68-year-old male who was being followed up for a small left renal mass without treatment. Two years later, computed tomography (CT) showed enlarged cervical and para-aortic lymph nodes, and lymph node biopsy suggested metastases of the cancer. After resection of the renal tumor, we performed pararenal aortic lymph node biopsy, and we diagnosed the case as papillary renal cell carcinoma type 1 with lymph node metastasis. The combination of ipilimumab and nivolumab each metastatic site showed regression on CT. Since immune-related adverse events occurred during the therapy nivolumab was discontinued, but partial response of the metastases was maintained.

(Summary) The influence of the console surgeon on the feasibility and outcome of various robot-assisted surgeries has been evaluated. These variables may be partially affected by the skills of the patient-side surgeon (PSS), but this has not been evaluated using objective data. This study aimed to describe the surgical techniques of the PSS in robot-assisted radical cystectomy (RARC) and intracorporeal ileal conduit (ICIC) urinary diversion and objectively examine the changes in surgical outcomes with increasing PSS experience. During a 3-year period, 28 men underwent RARC and ICIC urinary diversion. Clinical characteristics and surgical outcomes were compared between patients who underwent surgery early (first half group) or late in the study period (second half group). The pre-docking incision enabled easy specimen removal. The glove port technique widened the working space of the PSS. The stay suture allowed the PSS to control the distal portion of the conduit, facilitating the passage of the ureteral stents. During stoma creation, pneumoperitoneum pressure was lost by opening the abdominal cavity. To overcome this problem, the robotic arm was used to lift the abdominal wall to maintain the surgical field and facilitate the PSS procedure. Compared with the first half group, the second half group had significantly shorter times for urinary diversion (202 min vs 148 min, p < 0.001), ileal isolation and anastomosis (73 min vs 45 min, p < 0.001), and stenting (23.0 min vs 6.5 min, p < 0.001). As the experience of the PSS increased, the time of the PSS procedures decreased.

(Summary) Objectives : To evaluate whether virtual partial nephrectomy images could help surgeons identify vascular and collecting system around tumors during actual surgery. Materials & methods : We retrospectively analyzed 36 patients who underwent robot-assisted partial nephrectomy (RAPN) between 2016 and 2017. Virtual partial nephrectomy images were created from preoperative CT images using computer software, and then analyzed. For analysis, blood vessels and collecting system portions within a 5-mm-thick safety margin around the tumor were examined. During analysis, we predicted whether targeted vasculature around the tumor would require clipping or suturing during surgery, and also whether the collecting system would require opening during resection. Surgical outcomes for virtual partial nephrectomy analyses and actual RAPNs were compared and analyzed for sensitivity and specificity. Results : In 36 cases, 119 arteries and 100 veins were targeted on virtual partial nephrectomy images. Arterial suturing or clipping for hemostasis showed a sensitivity and specificity of 83.3% and 84.5%, respectively. For veins, the sensitivity and specificity were 39.1% and 92.2%, respectively. Collecting system opening prediction sensitivity was 85.7%, and specificity was 65.2%. Conclusion : Virtual partial nephrectomy imaging is useful for RAPN planning, particularly regarding arteries and the collecting system. It is hoped that techniques for visualizing veins will improve. J. Med. Invest. 69 : 237-243, August, 2022.

(Summary) We describe two cases of locally advanced rectal cancer (LARC) treated with robot-assisted total pelvic exenteration (Ra-TPE) and intracorporeal ileal conduit (ICIC). The first case was in a 71-year-old man with LARC (RbP, T4bN2bM0, cStage IIIc). He was started on bevacizumab+S-1/oxaliplatin therapy in July 2019. In April 2020, he developed Fournier's gangrene due to subcutaneous penetration of rectal cancer. Emergency drainage and colostomy were performed simultaneously, and a percutaneous vesical fistula was created. In May 2020, Ra-TPE and ICIC were performed. Histopathological analysis revealed moderately differentiated tubular adenocarcinoma (ypT3N0, RM0). At postoperative 9 months, thoracoscopic right upper lobectomy was performed for a right metastatic lung tumor. At present, ie, at postoperative 12 months, the patient has been free of recurrence and metastasis, with a carcinoembryonic antigen (CEA) level of 1.4 ng/ml and carcinoma antigen (CA) 19-9 level of 11 U/ml. The second case was in a 61-year-old man with fistula-associated anal cancer (PRb, T4N3M1b, cStage IVb). In April 2019, he was started on FOLFOXIRI+cetuximab therapy. In August 2020, Ra-TPE, ICIC, and transperineal total mesenteric excision were performed. Histopathological analysis revealed adenocarcinoma (ypT4N0, RM0). At postoperative 11 months, thoracoscopic left lower lobectomy was performed for a left metastatic lung tumor. At present, ie, at postoperative 12 months, the patient remains free of recurrence and metastasis, with a CEA level of 7.3 ng/ml and CA19-9 level of 12 U/ml. Ra-TPE, which allows transperineal removal of a specimen, can be performed as a minimally invasive surgery in combination with ICIC.

(Summary) While robot-assisted radical cystoprostatectomy (RARC) for locally advanced prostate cancer (LAPC) may sometimes prove to be excessive treatment, it can significantly reduce the risk of positive surgical margins and lower urinary tract obstruction in some cases. Here, we report a case of LAPC treated with RARC in a patient with right hydronephrosis due to bladder infiltration and left hypoplastic kidney. A 71-year-old man presented with frequent urination in August 2019. Prostate-specific antigen (PSA) level was 8.633 ng/ml, and magnetic resonance imaging led to the suspicion that the prostate cancer extended beyond the prostate capsule without distant metastasis. Prostatic biopsy revealed Gleason score 10 (5+5) adenocarcinoma in 8 out of 8 specimens. We diagnosed left hypoplastic kidney and LAPC with right hydronephrosis due to bladder infiltration. We performed percutaneous right nephrostomy and started neoadjuvant hormone therapy. RARC and intracorporeal ileal conduit were performed in March 2020. The prostate was adherent to the anterior surface of the rectum and was difficult to remove. At present, five months after the surgery, the patient remains free of recurrence and metastasis with PSA level <0.003 ng/ml. RARC for LAPC with bladder infiltration can be an effective therapeutic strategy in some cases.

(Summary) Purpose : To evaluate the efficacy of the direct grasping technique using pean forceps under fluoroscopic guidance for ureteral stent replacement in women. Methods : Between April 2018 and September 2020, 28 female patients underwent ureteral stent replacements at our facility, and 184 stent replacement procedures were performed. A total of 127 stents were replaced using pean forceps under fluoroscopic guidance (pean forceps group), and 57 stents were replaced using the cystoscope (cystoscopy group). Clinical characteristics and surgical outcomes were compared between the groups. Results : All stents were successfully replaced. There was a statistically significant difference in the procedure time between the two groups (median [interquartile range], pean forceps group : 10.8 [8.2-13.9] minutes vs. cystoscopy group : 15.8 [11.1-20.9] minutes, P < 0.001). There were no intraoperative complications in either group and no difference in the incidence of postoperative complications (pean forceps group : 1.6% vs. cystoscopy group : 1.8%, P = 1.000). Fluoroscopy time was longer in the pean forceps group, although this difference was not statistically significant (pean forceps group : 38.9 [22.6-60.1] seconds vs. cystoscopy group : 33.0 [20.0-48.9] seconds, P = 0.0558). Conclusion : The direct grasping technique using pean forceps under fluoroscopy may be a beneficial alternative to cystoscopy for ureteral stent replacement in women. J. Med.

(Summary) We report a case of bladder diverticulum presumably caused by lower urinary tract dysfunction due to pelvic organ prolapse (POP) simultaneously treated with transurethral coagulation (TUC) of the bladder diverticulum and laparoscopic sacrocolpopexy (LSC). A literature search showed this is the first report of bladder diverticulum and POP surgically treated at the same time. A 71-year-old woman was referred to our hospital for the treatment of cystocele. She had both storage and voiding symptoms. She had a POPQ stage III cystocele and stage I uterine prolapse. Ultrasonography and computed tomographic scan showed a large volume of residual urine along with a bladder diverticulum. Since urodynamic studies revealed a low compliance bladder and obstruction, we opined that the lower urinary tract symptoms were induced by the cystocele. TUC of the bladder diverticulum and LSC were performed at the same time. After the operation, clean intermittent catheterization (CIC) was needed once a day for one month. Gradually, residual urine decreased and CIC became unnecessary. The bladder diverticulum disappeared, and there has been no recurrence of POP.

(Summary) We report a case of left renal angiomyolipoma extending into the renal vein. A 67-year-old woman showed a left renal tumor which was 6 cm in diameter and had density equal to fat tissue in computed tomography. We suspected liposarcoma and performed radical nephrectomy and resection of thrombus. The pathological diagnosis was angiomyolipoma with no malignancy. To our knowledge, renal angiomyolipoma with tumor thrombus has been reported in 62 cases, and pulmonary embolism developed in 9 of these cases. We conclude that surgical treatment is effective in treating angiomyolipoma with tumor thrombus.

(Summary) Although diagnostic imaging techniques have evolved in recent years, the accuracy of ureteral cancer detection and depth is still low. In particular, ureteral cancer depth diagnosis technology is important before drug therapy, and its early development is required. In this study, we conducted a pilot study to construct a system to predict the depth of ureteral cancer from CT images using AI (artificial intelligence) based on deep learning (deep learning). Methods: We evaluated the learning rate of the system by classifying CT images of 30 cases of lower ureteral cancer out of 157 cases of ureteral cancer treated by total nephroureteral resection from 2009 to 2020 at the University of Tokushima Hospital. The location of cancer was determined by comparing the location of cancer in the macro image of the resected specimen with the location of cancer in the CT image, and each CT slice was classified as "containing cancer" or "not containing cancer". The correct rate of lower ureteral cancer determination in CT images by the AI was 99.94% when tested with trained data at the time of 100 training cycles, and 99.15% when tested with un-trained data. No over-learning was observed in this study. [Conclusion] We evaluated lower ureteral cancer in CT images using AI. It was considered possible to learn to determine the presence or absence of cancer from CT images in this setting. In the future, we will use AI to identify the location and predict the depth of ureteral cancer from CT images, and aim to establish an evaluation model that can be applied in actual clinical practice.
