Yonsei nomogram: A predictive model of new-onset chronic kidney disease after on-clamp partial nephrectomy in patients with T1 renal tumors.

Objectives: To develop a predictive nomogram for chronic kidney disease-free survival probability in the long term after partial nephrectomy.

Methods: A retrospective analysis was carried out of 698 patients with T1 renal tumors undergoing partial nephrectomy at a tertiary academic institution. A multivariable Cox regression analysis was carried out based on parameters proven to have an impact on postoperative renal function.

Prostate-specific antigen 10-20 ng/mL: A predictor of degree of upgrading to ≥8 among patients with biopsy Gleason score 6.

Purpose: This study aimed to identify the predictors of upgrading and degree of upgrading among patients who have initial Gleason score (GS) 6 treated with robot-assisted radical prostatectomy (RARP).

Materials And Methods: A retrospective review of the data of 359 men with an initial biopsy GS 6, localized prostate cancer who underwent RARP between July 2005 to June 2010 was performed. They were grouped into group 1 (nonupgrade) and group 2 (upgraded) based on their prostatectomy specimen GS.

Perioperative and short-term outcomes of Retzius-sparing robot-assisted laparoscopic radical prostatectomy stratified by gland size.

Objective: To investigate the effect of preoperative prostate volume (PV) on the perioperative, continence and early oncological outcomes among patients treated with Retzius-sparing robot-assisted laparoscopic radical prostatectomy (RS-RALP).

Patients And Methods: This is a retrospective analysis of 294 patients with organ-confined prostate cancer treated with RS-RALP in a high-volume centre from November 2012 to February 2015. Patients were divided into three groups based on their transrectal ultrasonography estimated PV as follows: group 1, <40 mL (231 patients); group 2, 40-60 mL (47); group 3, >60 mL (16).
