[Construction of digital three-dimensional models of renal stones and virtual surgery simulation].

Objective: To construct three-dimensional (3D) models of renal stones and perform percutaneous nephrolithotomy (PCNL) virtual surgery simulation. Methods CT images were obtained from 8 patients with renal stones. Images segmentation and reconstruction were performed using MIMICS 10.

[Single-port laparoscopic surgery for radical nephrectomy: report of 22 cases].

Objective: [corrected] To evaluate the method and technique of single-port laparoscopic radical nephrectomy.

Methods: Form January 2009 to September 2011, 22 patients with renal carcinoma were treated with single-port laparoscopic radical nephrectomy. An incision about 5 cm in length was made through the umbilicus or in the postaxillary line under the 12th rib to establish the peritoneal or retroperitoneal working space.

[Percutaneous nephrolithotomy through the upper pole calix access for complicated renal calculi: report of 581 cases].

Objective: To discuss the optimal approach of percutaneous nephrolithotomy (PCNL) for treatment of complicated renal calculi.

Methods: A total of 581 patients with complicated renal calculus were treated by PCNL through the upper pole calix access. Of the 581 patients, 55 had multiple upper pole calculi, 136 had staghorn stones, 145 had partial staghorn stones, and 245 had multiple renal calculi.

[Laparoscopic radical cystectomy and detenial sigmoid colon orthotopic neobladder reconstruction for bladder tumor in a 3-year-old boy].

Objective: To present a case of laparoscopic radical cystectomy and detenial sigmoid colon orthotopic neobladder reconstruction for bladder tumor in a child.

Methods: A 3-year-old boy with bladder rhabdomyosarcoma underwent laparoscopic radical cystectomy and detenial sigmoid colon orthotopic neobladder reconstruction. The bilateral pelvic lymphadenectomy and cystectomy were performed laparoscopically, and removal of the mobilized specimens and urinary diversion operation were managed through enlarged abdomen incision.

[Application of silk fibroin film for repairing rabbit urethral defect].

Objective: To evaluate the effect of silk fibroin film for repairing urethral defect in rabbits.

Methods: Twenty-four male New Zealand rabbits were randomized into experimental group, control group I and control group II. In the experimental group, a urethral defect of 1.
