The absence of spermatogenesis in radical orchiectomy specimen is associated with advanced-stage nonseminomatous testicular cancer.

Background: To assess if clinical, pathological, and spermatogenesis factors are associated with clinical staging in patients with testicular germ cell tumors.

Patients And Methods: We retrospectively reviewed the pathology reports and slides from 267 men who underwent radical orchiectomy for testicular cancer at our institution during 1998-2019. Histologic slides were reviewed and the presence of mature spermatozoa was documented.

Tubeless supra-costal percutaneous nephrolithotomy is associated with significantly less hydrothorax: a prospective randomized clinical study.

Objectives: To evaluate prospectively whether a tubeless (JJ stent-only) percutaneous nephrolithotomy (PCNL) might reduce the risk of hydrothorax, compared to an approach where a nephrostomy tube is left.

Materials And Methods: We conducted a two-arm open-label prospective randomized study (NCT02036398) comparing tubeless supra-costal PCNL (with a JJ stent only) to standard PCNL (with nephrostomy tube and JJ stent) using intention-to-treat (ITT) and per-protocol (PP) analyses. All patients underwent a standard single-stage prone supra-costal procedure with single-tract access.

The "old" 15 mm renal stone size limit for RIRS remains a clinically significant threshold size.

Purpose: To investigate the performance of retrograde intrarenal surgery (RIRS) for the 1-2 cm renal stone size range in comparison to smaller stones.

Materials And Methods: From a data base of 3000 ureteroscopies between 2004 and 2014, 635 consecutive patients underwent RIRS for renal stones. Patients were divided to three groups according to their renal stone size (<10, 10-15, 15-20 mm).

Predictors of spermatogenesis in radical orchiectomy specimen and potential implications for patients with testicular cancer.

Objective: To assess the ability of semen analysis and other patients' characteristics to predict the presence of spermatozoa in radical orchiectomy pathological specimen, and describe potential implications for patients with azoospermia and testis cancer.

Design: Retrospective cohort study.

Setting: Tertiary hospital.
