Global minimally invasive pyeloplasty study in children: Results from the Pediatric Urology Expert Group of the European Association of Urology Young Academic Urologists working party.

Introduction: Minimally invasive pyeloplasty (MIP) for ureteropelvic junction (UPJ) obstruction in children has gained popularity over the past decade as an alternative to open surgery. The present study aimed to identify the factors affecting complication rates of MIP in children, and to compare the outcomes of laparoscopic (LP) and robotic-assisted laparoscopic pyeloplasty (RALP).

Materials And Methods: The perioperative data of 783 pediatric patients (<18 years old) from 15 academic centers who underwent either LP or RALP with an Anderson Hynes dismembered pyeloplasty technique were retrospectively evaluated.

Nephrometry scoring systems for surgical decision-making in nephron-sparing surgery.

Purpose Of Review: Herein, we review the various recently published nephrometry scoring systems and the available data on their ability to predict clinical outcomes and their usefulness for new operative techniques.

Recent Findings: Several studies showed that the preoperative aspects and dimensions used for anatomical classification score, the RENAL system, and the centrality index are reproducible and able to predict certain clinical intraoperative and postoperative variables in patients undergoing nephron-sparing surgery. Addition of variables, such as the BMI, to the pre-existing scores might improve their predictive abilities.

Use of self-retaining barbed sutures decreases cold ischemia time in open nephron-sparing surgery.

Purpose: In the present study, we aimed to determine whether the use of self-retaining barbed sutures (SRBS) instead of conventional sutures during open partial nephrectomy leads to improved surgical outcomes.

Patients, Materials And Methods: A retrospective analysis of 50 consecutive patients who underwent open partial nephrectomy for a unicentric renal tumor was performed. In 15 patients, SRBS were used for parenchymal repair during open partial nephrectomy, and in 35 patients, conventional sutures were used.

Transperineal template-guided biopsy for diagnosis of prostate cancer in patients with at least two prior negative biopsies.

Objective: To evaluate the prostate cancer (PCa) detection rate, PCa location, PCa significance and complications of a standardized 24-core template-guided transperineal biopsy (TPB) approach in patients with at least two negative transrectal biopsies.

Methods: We prospectively recruited 50 men who had at least two negative transrectal ultrasound-guided extended biopsies in the past 24 months, a prostate-specific antigen (PSA) < 20 ng/mL, a prostate volume < 100 mL, and life expectancy of at least 90 % at 10 years. All patients underwent a standardized 24-core template-guided TPB biopsy.

Bladder outlet obstruction (BOO) in men with castration-resistant prostate cancer.

Objective: To evaluate the frequency of bladder outlet obstruction (BOO) and detrusor overactivity (DO) in patients with castration-resistant prostate cancer (CRPC) and lower urinary tract symptoms (LUTS).

Patients And Methods: Our prospective urodynamics database was queried. Inclusion criteria were CRPC and an International Prostate Symptom Score (IPSS) ≥ 20.
