Purpose: Upward stone migration is a significant problem during ureteroscopic lithotripsy (URSL) for upper ureteral stone, especially in absence of a ureteral occlusion device. In this study, we evaluated the novel strategy of reverse Trendelenburg position (RTP) and intraoperative diuresis for URSL without ureteral occlusion devices to avoid upward migration.

Materials And Methods: From March 2018 to May 2020, a total of 119 URSLs were performed for upper ureteral stone (6-15 mm) with 67 procedures in RTP and 52 procedures in conventional lithotomy position (CLP).

Objective: To evaluate retroperitoneoscopic renal pedicle lymphatic disconnection (RRPLD) for chyluria in the setting of complex renal vasculature and compare those outcomes with the RRPLD outcomes of patients with normal renal vasculature.

Materials And Methods: From December 2002 to December 2011, RRPLD was performed in 14 patients with complex renal vasculature and 64 patients with normal renal vasculature. Preoperative multislice spiral computed tomography angiography for renal vessels was done on 5 patients with complex vasculature.

Purpose: To evaluate the feasibility and safety of the closed technique (CT) with Veress needle for the creation of retroperitoneal working space (RWS) for the retroperitoneoscopic ablation of symptomatic renal cysts by comparison with the open technique (OT).

Material And Methods: In this series of 412 patients who underwent retroperitoneoscopic ablation of symptomatic renal cysts, RWS was created by OT in 231 patients and CT in 181 patients, respectively. The time to create RWS, operative time, and complications were analyzed.

Objective: To identify whether integrinβ1 subunit is responsible for the resistance of bladder cancer cell to the therapeutic drug mitomycin-C (MMC), when grown on fibronectin (FN).

Materials And Methods: The expression of integrinβ1 on bladder cancer T24 and 5637 cells was examined by the flow cytometer. The adhesion of cells to plates with the absence or presence of FN was determined.

Background And Purpose: The retroperitoneoscopic renal pedicle lymphatic disconnection has been performed mainly via a renal adipose (RA) capsule approach. In this study, we reported a novel technique via extra-adipose (EA) capsule approach and compared the two approaches for intractable chyluria.

Patients And Methods: From December 2002 to March 2008, retroperitoneoscopic renal pedicle lymphatic disconnection was performed on 41 patients with 23 EA and 18 RA.

Aim: The activation of extracellular signal-regulated kinase (ERK)1/2 protects against ischemic-reperfusion injury. Whether ERK1/2 mediates the cardioprotection of sevoflurane postconditioning is unknown. We tested whether sevoflurane postconditioning produces cardioprotection via an ERK1/2-dependent mechanism.

Objective: To discuss the value of pre-operative semen analysis of patients with varicocele as a predictive restore index of sperm motility and fertilizing capacity after varicocelectomy.

Methods: Semen analysis was carried out with computer-aided sperm analyzer in 107 patients with varicocele and all patients were referred to the clinic with diagnosis of male infertility. Stratification of patients as group A (n = 32), B ( n = 36) and C (n = 39) was based on pre-operative total motile sperm count (TMSC).
