Accuracy of sentinel lymph node biopsy for inguinal lymph node staging of penile squamous cell carcinoma: systematic review and meta-analysis of the literature.

Purpose: Sentinel lymph node biopsy is emerging as a promising method for inguinal lymph node staging of penile squamous cell carcinoma. In the current systematic review we evaluated the accuracy of sentinel lymph node biopsy for inguinal lymph node staging of penile squamous cell carcinoma and studied possible influential factors.

Materials And Methods: MEDLINE®, Scopus®, ISI®, Ovid SP®, Springer, ScienceDirect® and Google™ Scholar were searched by the key words "(penile OR penis) AND sentinel".

Ureteroscopic and extracorporeal shock wave lithotripsy for rather large renal pelvis calculi.

Introduction: The aim of this study was to compare the results and complications of extracorporeal shock wave lithotripsy (SWL) plus retrograde ureteroscopic lithotripsy using laser and pneumatic lithotriptors with SWL monotherapy for renal pelvic calculi between 2 cm and 3 cm.

Materials And Methods: A total of 55 patients with 2- to 3-cm pelvic calculi were assigned into groups 1 and 2, including 22 and 33 patients, respectively. Patients in group 1 first underwent laser pneumatic lithotripsy and insertion of a double-J ureteral catheter and then underwent SWL 2 to 4 weeks thereafter.
