Introduction: Ureteropelvic junction obstruction associated with ureteral duplication is rare, with prevalence reported to be around 2-7%. Ureteropelvic junction obstruction of the lower pole with both complete and incomplete duplex systems is a common cause of obstruction. Here, we report a case of ureteropelvic junction obstruction associated with incomplete ureteral duplication of the solitary kidney successfully treated by pyeloureterostomy.

- The study aimed to assess the impact of transrectal high-intensity focused ultrasound (HIFU) on urinary function specifically in the anterior transition zone (TZ) of patients with localized prostate cancer (PCa).
- A total of 90 patients treated between 2016 and 2018 were evaluated pre- and post-treatment using various urinary function metrics like the International Prostate Symptom Score (IPSS).
- Results indicated significant deterioration in urinary function at 1 month post-treatment for those in the TZ group compared to other regions, with higher rates of complications such as urinary retention and urethral stricture observed in the TZ group.
Purpose: To evaluate the surgical feasibility and postoperative cosmesis of a novel transumbilical laparoendoscopic single-site (LESS) surgical approach involving Y-shaped incisions and three-flap umbilicoplasty in urachal remnant patients.
Methods: Patients with symptomatic urachal remnants who underwent either conventional laparoscopic surgery (CL group, n = 21) or LESS surgery with Y-shaped incisions and three-flap umbilicoplasty (LESS group, n = 36) between May 2010 and September 2019 were retrospectively assessed. Perioperative factors and postoperative esthetic outcomes were compared between the groups using univariate and multivariate analyses.
Objective: To evaluate functional outcomes over a year for benign prostatic hyperplasia treated with thulium laser enucleation of the prostate or bipolar transurethral resection of the prostate.
Methods: In this study, we prospectively included 140 patients who were treated for benign prostatic hyperplasia from April 2017 to February 2019. A randomization list was used for non-blind assignment to treatment groups (thulium laser enucleation of the prostate or bipolar transurethral resection of the prostate).
Article Synopsis
- Robot-assisted radical prostatectomy (RARP) is increasingly used for localized prostate cancer treatment, but exact patient factors affecting surgical time, especially pelvic visceral fat (PVF) volume, have not been systematically studied.
- A study involving 405 RARP patients from 2014 to 2019 found that significant factors for prolonged surgical console time included larger PVF, smaller working space (WS), nerve-sparing procedures, and higher body mass index (BMI).
- The findings suggest that both PVF and WS are critical in determining surgical time, with BMI and pelvic width being practical alternatives for gauging the complexity of the procedure.
Objective: We evaluated the effect of neoadjuvant chemotherapy in patients undergoing radical cystectomy for urothelial bladder cancer.
Methods: We retrospectively examined 140 consecutive patients with muscle-invasive bladder cancer (clinical stage T2 to T4 and N0) who underwent radical cystectomy with or without neoadjuvant chemotherapy at four academic institutions between January 2006 and December 2016. Patients were categorized into the neoadjuvant chemotherapy group (those who underwent treatment with any neoadjuvant chemotherapy regimen; n = 69) and the non-neoadjuvant chemotherapy group (those who did not receive any neoadjuvant chemotherapy regimen; n = 71).

A 28-year-old man was hospitalized with advancing paraplegia. Under the diagnosis of Guillain-Barre syndrome, steroid pulse therapy was administered and plasmapheresis was performed. However, the paraplegia gradually progressed.

- The study evaluated the use of weekly low-dose docetaxel chemotherapy in 39 patients with castration-resistant prostate cancer (CRPC) from 2007 to 2014, focusing on effectiveness, side effects, and tolerability.
- Median patient age was 71, with a 33% reduction in prostate-specific antigen (PSA) levels observed in some patients, linking PSA decrease to better overall survival outcomes.
- The treatment was mostly completed without major interruptions, indicating that low-dose docetaxel is a feasible and relatively safe option for CRPC patients, although some experienced significant side effects.
Article Synopsis
- - An 80-year-old man developed a rash on his abdomen after receiving leuprorelin acetate injections for prostate cancer, raising concerns about a potential metastatic skin tumor following his gastric cancer surgery.
- - Histological analysis identified a foreign-body granuloma in the subcutaneous tissue, confirming it as a side effect of the leuprorelin treatment rather than a cancer spread.
- - The study aims to analyze clinical findings related to granuloma formation in 335 cases treated with leuprorelin acetate at the hospital, highlighting this common side effect among urologists.
Objectives: To develop a modified technique of "total pelvic floor reconstruction" during non-nerve-sparing laparoscopic radical prostatectomy, and to determine its effect on postoperative urinary outcomes.
Methods: A total of 128 patients who underwent non-nerve-sparing laparoscopic radical prostatectomy were evaluated, including 81 with total pelvic floor reconstruction and 47 with non-total pelvic floor reconstruction. Nerve-sparing cases were excluded.
