[Trans-Douglas Retzius' space-sparing robot-assisted simple prostatectomy for large-volume benign prostate hyperplasia].

Objective: To report the safety and efficacy of trans-Douglas Retzius' space-sparing robot-assisted simple prostatectomy (RSS-RASP) in the treatment of large-volume BPH.

Methods: This retrospective study included 24 cases of large-volume (>80 ml) BPH treated by trans-Douglas RSS-RASP from August 2019 to June 2021. The patients ranged in age from 55 to 80 (mean 68.

[Nerve-sparing robot-assisted laparoscopic radical cystectomy: Clinical application and effect].

Objective: To investigate the clinical feasibility and effect of nerve-sparing robot-assisted laparoscopic radical cystectomy (NSRA-LSRC).

Methods: We retrospectively reviewed the clinical data on 12 cases of NSRA-LSRC performed from March 2016 to May 2018. The patients were aged 45 to 65 years old and all potent before surgery, with a mean IIEF-5 score of >17.

[Retzius-sparing robot-assisted laparoscopic radical prostatectomy for early-stage prostate cancer (with video)].

Objective: To investigate the application of Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) in the treatment of early-stage prostate cancer.

Methods: We retrospectively analyzed the clinical data about 10 cases of early-stage prostate cancer treated by RS-RARP with the Da Vinci Robot Surgical System from September to October 2016.

Results: All the operations were successfully completed without positive surgical margins.

Perineural invasion status, Gleason score and number of positive cores in biopsy pathology are predictors of positive surgical margin following laparoscopic radical prostatectomy.

This study was designed to define possible preoperative predictors of positive surgical margin after laparoscopic radical prostatectomy. We retrospectively analyzed the records of 296 patients with prostate cancer diagnosed by prostate biopsy, and eventually treated with laparoscopic radical prostatectomy. The prognostic impact of age, prostate volume, preoperative prostate-specific antigen, biopsy Gleason score, maximum percentage tumor per core, number of positive cores, biopsy perineural invasion, capsule invasion on imaging, and tumor laterality on surgical margin was assessed.

[Clinical analysis of primary hyperparathyroidism with kidney stones: 23 cases report].

Objective: To discuss the clinical characteristics of primary hyperparathyroidism (PHPT) with kidney stones.

Methods: The clinical data of 23 cases undergoing diagnostic evaluation and surgery for PHPT combined with kidney stones between January 2004 and February 2012 was retrospectively analyzed. The 23 cases had undergone preoperative parathyroid neck color ultrasound, CT or (99)mTc-methoxy isobutyl isonitrile ((99)mTc-MIBI) diagnosis.

[Mid-term follow-up results of laparoscopic radiofrequency ablation for renal cell carcinoma of T1aN0M0 stage].

Objective: To determine the effect of laparoscopic radiofrequency ablation of T1aN0M0 renal cell carcinoma (RCC) with regular follow-up.

Methods: All patients underwent surgery from March 2006 to March 2009. Eight cases were solitary kidney.

[Radiofrequency ablation-assisted laparoscopic partial nephrectomy without renal hilar vessel clamping: a report of 14 cases].

Objective: To evaluate the clinical feasibility of radiofrequency ablation-assisted laparoscopic partial nephrectomy (RF-LCPN) without renal hilar vessel clamping.

Methods: From January 2009 to June 2010, 14 cases with renal tumors were treated with RF-LCPN. The mean tumor size was 3.

[A retrospective study comparing the clinical efficacy of laparoscopic cryoablation and partial nephrectomy for renal cell carcinoma].

Objective: To compare the clinical outcomes of laparoscopic cryoablation (LCA) and laparoscopic partial nephrectomy (LPN) in the treatment of renal cell carcinoma (RCC).

Methods: Between April 2005 and March 2009, 47 patients were treated with minimally invasive nephron sparing surgery (LPN or LCA) for RCC. The LCA group included 18 selected primary RCC cases (14 men and 4 women, mean age 63 years).

[Erectile function in male kidney transplant recipients and effects of different methods of renal arterial anastomosis].

Objective: To evaluate erectile function in men with renal failure before and after kidney transplantation and the effects of different methods of renal arterial anastomosis.

Methods: Fifty-five married males, aged 22-50 years, who had received kidney transplantation at least one year before and whose serum creatinine was under 200 micromol/L , were selected in the study. The end-to-end revascularization to the internal iliac artery was accomplished in 39 of them, and the end-to-side revascularization to the external iliac artery was conducted in 16.
