Long-term survival after female pelvic organ-sparing radical cystectomy versus standard radical cystectomy: a multi-institutional propensity score-matched analysis.

Background: The application of pelvic organ preserving-radical cystectomy (POPRC) in female patients with bladder cancer has attracted more and more attention in recent years. In the current study, the authors aim to compare the long-term oncological outcomes of POPRC versus standard radical cystectomy (SRC) in a large multicenter retrospective cohort.

Patients And Methods: Data on female patients with bladder cancer who underwent POPRC or SRC in January 2006 and April 2018 were included from three Chinese urological centers.

De novo upper tract urothelial carcinoma after renal transplantation: a single-center experience in China.

Background: Long-term prognosis and risk factors of de novo upper tract urothelial carcinoma after renal transplantation were rarely studied. Thus, the aim of this study was to investigate the clinical features, risk factors, and long-term prognosis of de novo upper tract urothelial carcinoma after renal transplantation, especially the impact of aristolochic acid on tumor, using a large sample.

Methods: 106 patients were enrolled in retrospective study.

Etiology, characteristics and management of ureteric injury: experience from a nationwide study.

Background: To investigate the common etiologies, characteristics, and management of ureteric injury.

Methods: A nationwide study was performed in 38 medical centers from Mar 2017 to Mar 2019. The data of patients with ureteric injury were retrospectively collected.

Etiology and Ureteral Reconstruction Strategy for Iatrogenic Ureteral Injuries: A Retrospective Single-Center Experience.

Objective: To analyze the etiology, characteristics, and ureteral reconstruction strategies of iatrogenic ureteric injuries in a high-volume center.

Methods: Between September 2010 and August 2019, we retrospectively collected patients who underwent ureteral reconstruction due to iatrogenic ureteric injuries. Patient profiles, laboratory data, imaging studies, perioperative data, and complications were recorded.

A laparoscopic vascular blocking forceps used for renal carcinoma combined with tumor thrombus.

Objectives:: To discuss the feasibility and efficacy of a laparoscopic vessel blocking forceps in laparoscopic inferior vena cava (IVC) thrombectomy (–3).

Materials And Methods:: The patient was secured in a left lateral decubitus position. The surgical field was built with 4-trocar.

Experience managing distal ureteral strictures with Boari flap-psoas hitch and comparison of open and laparoscopic procedures.

Background: To summarize our experience with the Boari flap-psoas hitch and compare the indications, perioperative data and outcomes between open and laparoscopic procedures.

Methods: This study retrospectively reviewed 35 patients with complex distal ureteral stricture between January 2015 and April 2019. All patients were treated with Boari flap-psoas hitch by either an open or a laparoscopic procedure.

Onlay Repair Technique for the Management of Ureteral Strictures: A Comprehensive Review.

Ureteroplasty using onlay grafts or flaps emerged as an innovative procedure for the management of proximal and midureteral strictures. Autologous grafts or flaps used commonly in ureteroplasty include the oral mucosae, bladder mucosae, ileal mucosae, and appendiceal mucosae. Oral mucosa grafts, especially buccal mucosa grafts (BMGs), have gained wide acceptance as a graft choice for ureteroplasty.

Urothelial Carcinoma Detection Based on Copy Number Profiles of Urinary Cell-Free DNA by Shallow Whole-Genome Sequencing.

Background: Current noninvasive assays for urothelial carcinoma (UC) lack clinical sensitivity and specificity. Given the utility of plasma cell-free DNA (cfDNA) biomarkers, the development of urinary cfDNA biomarkers may improve the diagnostic sensitivity.

Methods: We assessed copy number alterations (CNAs) by shallow genome-wide sequencing of urinary cfDNA in 95 cancer-free individuals and 65 patients with UC, 58 with kidney cancer, and 45 with prostate cancer.

Technical considerations and outcomes for ileal ureter replacement: a retrospective study in China.

Background: Ileal ureter replacement is an alternative treatment for various length ureter defects. We present our experience and outcome of ileal ureter replacement in China.

Methods: We retrospectively collected data of patients who underwent ileal ureter replacement between January 2010 and January 2015.

Laparoscopic Radical Cystectomy With Extracorporeal Neobladder: Our Initial Experience.

Objective: To illustrate our technique to construct the Institute of Urology Peking University (IUPU) orthotopic ileal bladder and present our initial experience.

Methods: From August 2017 to April 2018, 12 patients with bladder cancer underwent radical cystectomy (RC), pelvic lymph node dissection and extracorporeal construction of an IUPU neobladder (IUPUB) by an experienced surgeon. We present the demographic, clinicopathologic, perioperative, and follow-up data.

Head-to-Head Comparison of Modified Laparoscopic Pyeloplasty and Robot-Assisted Pyeloplasty for Ureteropelvic Junction Obstruction in China.

Objective: To compare the outcomes of modified laparoscopic pyeloplasty (LP) and robot-assisted pyeloplasty (RLP) for ureteropelvic junction obstruction (UPJO) in China patients.

Materials And Methods: We retrospectively reviewed the medical records of patients who underwent modified LP and RLP using a transperitoneal laparoscopic approach at 2 different medical institutions between October 2009 and November 2017.

Results: Seventy-six patients underwent modified LP and 140 patients underwent RLP.
