Robot-assisted intracorporeal ileal conduit urinary diversion: A two-center comparative study of Bricker versus Wallace ureteroileal anastomosis.

Introduction: 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).

Methods: 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.

Impact of early urinary catheter removal on successful voiding and physical function in stroke patients.

Objective: 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.

Methods: 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 importance of laparoscopic surgery for young urologists remains unwavering even in the era of robot-assisted surgery.

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.

Effect of Positive Biopsy Core Rate on Low-dose-rate Brachytherapy Outcomes in Intermediate-risk Prostate Cancer.

Background/aim: Intermediate-risk prostate cancer (PCa) is a highly heterogeneous disease. Although low-dose-rate brachytherapy (LDR-BT) is mainly used for low- to intermediate-risk PCa, limited reports have evaluated the detailed differences in outcomes, including differences between patients with ISUP grade group (GG) 2 and GG3 intermediate-risk PCa. This study aimed to investigate the differences in outcomes between intermediate-risk Japanese patients with GG2 and GG3 PCa who underwent LDR-BT.

Lymph node dissection during radical cystectomy for bladder cancer: A two-center comparative study of robotic versus open surgery.

Introduction: 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).

Methods: 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.

Background: The study aimed to examine the significance of insulin receptor (INSR) expression in predicting resistance to axitinib in clear cell renal cell carcinoma (ccRCC).

Methods: Clinicopathological data were collected from 36 consecutive patients with metastatic RCC who received axitinib. Thirty-three primary tumours were obtained for immunohistochemistry.

The impact of nutritional status and changes of body composition on the prognosis of metastatic renal cell carcinoma patients.

Purpose: This study aimed to analyze the impact of patients' nutritional status and changes in body composition on the prognosis of metastatic renal cell carcinoma (mRCC) patients who received systemic therapy with tyrosine kinase inhibitors (TKIs).

Methods: A total of 57 mRCC patients who received systemic therapy with TKIs as first-line therapy at our facility between November 2004 and October 2018 were included. The Prognostic Nutritional Index (PNI) was used to evaluate their nutritional status.

Efficacy of fresh-frozen cadaveric surgical training for arteriovenous fistula in vascular access.

Background: Creation of an arteriovenous fistula (AVF) as vascular access is a basic operation that should be learned by all surgeons involved in renal failure treatment. AVF creation is often challenging for inexperienced young surgeons because it requires comprehensive surgical techniques. For such young surgeons, we introduced cadaveric surgical training (CST) for AVF creation using fresh-frozen cadavers (FFCs).

Prostate-specific Antigen Levels Following Brachytherapy Impact Late Biochemical Recurrence in Japanese Patients With Localized Prostate Cancer.

Background/aim: Evaluation of long-term outcomes is essential for the successful treatment of localized prostate cancer; however, the risk of late recurrence following brachytherapy is still not clear. This study aimed to evaluate the long-term outcomes of low-dose-rate brachytherapy (LDR-BT) for localized prostate cancer in Japanese patients and identify factors associated with late recurrence after treatment.

Patients And Methods: This single-center, cohort study included patients who underwent LDR-BT at the Tokushima University Hospital in Japan between July 2004 and January 2015; 418 patients, who were followed-up at least 7 years after LDR-BT, were included in the study.

Assistent guide: A novel device for ureteral stent placement in robot-assisted intracorporeal ileal conduit.

Introduction: Ureteral stent placement in robot-assisted intracorporeal ileal conduit formation (RICIC) is more challenging than extracorporeal urinary diversion. We developed a novel dedicated device called the Assistent guide for safe and smooth performance of ureteral stent placement by the patient-side surgeon (PSS).

Methods: This study reviewed the clinical records of 59 patients underwent RICIC with a total of 110 ureteral stent placements: 59 stents were placed using the Assistent guide, and 51 stents were placed using a suction tip.

A propensity score matching study on robot-assisted radical cystectomy for older patients: comparison of intracorporeal ileal conduit and cutaneous ureterostomy.

Background: Robot-assisted radical cystectomy (RARC) and intracorporeal urinary diversion are less invasive than conventional procedures. However, for older patients, cutaneous ureterostomy (CUS) may be preferred because urinary diversion using the intestine has a high incidence of perioperative complications and is highly invasive. The purpose of this study was to demonstrate the safety and efficacy of intracorporeal ileal conduit (ICIC) compared with CUS in patients aged 75 years or older who underwent RARC.

Appropriate management reduces radiation exposure in daily urological practice.

Objectives: To identify and raise awareness of the radiation exposure of urologists due to X-ray fluoroscopic procedures in daily practice.

Methods: 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.

Efficacy of the Mercedes-Benz closure technique for vaginal reconstruction in female robot-assisted radical cystectomy.

Introduction: 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.

[Two Cases of Robot-Assisted Total Pelvic Exenteration and Intracorporeal Ileal Conduit for Locally Advanced Rectal Cancer].

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.

[A Case of Pappilary Renal Cell Caircinoma which Responded Well to the Combination Therapy of Ipilimumab and Nivolumab --A CASE REPORT-].

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.

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).

[A Case of Robot-Assisted Radical Cystoprostatectomy for Locally Advanced Prostate Cancer with Bladder Infiltration].

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.

The patient-side surgeon plays a key role in facilitating robot-assisted intracorporeal ileal conduit urinary diversion in men.

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.

[A Case of Pelvic Organ Prolapse and Bladder Diverticulum Surgically Treated at the Same Time].

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.
