Article Synopsis
- The study investigates how the shape of the prostate, as seen on MRI, affects the difficulty of robot-assisted laparoscopic radical prostatectomy (RALP).
- It reviewed data from 211 patients who underwent RALP, analyzing prostate volume and roundness in relation to console time, a measure of surgical difficulty.
- Findings show a weak correlation between prostate shape and console time, but spherical shapes in patients with larger prostates (≥40 cc) showed a stronger link to increased surgical difficulty.
In recent years, immune checkpoint inhibitors have attracted attention in treatment for urothelial carcinoma. However, many clinical trials included only patients who had adequate renal function. The efficacy of immune checkpoint inhibitors for hemodialysis patients had not been well-documented.

However, its role as a prognostic marker in cabazitaxel chemotherapy remains unclear. This study aimed to elucidate the clinical significance of serum testosterone levels before cabazitaxel chemotherapy.

- The study examined how certain factors predict sensitivity to cabazitaxel therapy in patients with metastatic castration-resistant prostate cancer (mCRPC) who have PTEN alterations.
- Out of 12 patients treated, 41% showed a positive response to cabazitaxel, and all of these had previously responded well to docetaxel therapy, indicating a link between responses to these treatments.
- Key findings showed that poor prior response to docetaxel and higher baseline PSA levels are significant predictors of a shorter progression-free survival with cabazitaxel, highlighting the cross-resistance between the two therapies.
Background: The relationship between guideline adherence for radical cystectomy of non-muscle-invasive bladder cancer and patient prognoses currently remains unclear. We investigated whether guideline adherence at the time of non-muscle-invasive bladder cancer affects the oncological outcomes of bladder cancer patients who underwent radical cystectomy.
Methods: Among 267 cTa-4N0-2M0 bladder cancer patients, 70 who underwent radical cystectomy under the non-muscle-invasive bladder cancer or muscle-invasive bladder cancer status that progressed from non-muscle-invasive bladder cancer were identified.
Ureterosciatic Hernia Treated with Laparoscopic Intraperitonization of the Ureter.
J Endourol Case Rep
September 2020
Ureterosciatic hernia (USH) is a rare benign disease. We report a case of USH treated with laparoscopic intraperitonization of the ureter. A 70-year-old woman was admitted to our hospital with right abdominal pain lasting for 2 months.

We report a rare case of urethral stone formation with brachytherapy seeds determined to be the nidus, which occurred 9 years after permanent seed brachytherapy for prostate cancer.
