[Effect and impact of holmium laser versus thulium laser enucleation of the prostate on erectile function].

Objective: To compare the effect and impact of holmium laser enucleation of the prostate (HoLEP) and 120-W thulium: YAG vapoenucleation of the prostate (ThuVEP) on erectile function in the treatment of benign prostatic hyperplasia (BPH).

Methods: We retrospectively analyzed 93 cases of symptomatic BPH treated by HoLEP or 120 W ThuVEP. We made comparisons between the two groups of patients in the baseline and postoperative clinical and surgical indexes as well as their IPSS, quality of life (QOL), maximum flow rate (Qmax), postvoid residual urine volume (PVR), and IIEF-EF scores before surgery and during the 12-month follow-up.

Efficacy and safety of 120-W thulium:yttrium-aluminum-garnet vapoenucleation of prostates compared with holmium laser enucleation of prostates for benign prostatic hyperplasia.

Background: This study compared the efficacy and safety between 120-W thulium:yttrium-aluminum-garnet (Tm:YAG) vapoenucleation of prostates (ThuVEP) and holmium laser enucleation of prostates (HoLEP) for patients with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH).

Methods: A retrospective analysis of 88 consecutive patients with symptomatic BPH was carried out, who underwent either 120-W ThuVEP or HoLEP nonrandomly. Patient demographics and peri-operative and 12-month follow-up data were analyzed with the International Prostate Symptom Score (IPSS), quality of life (QoL) score, maximum flow rate (Qmax), postvoid residual urine volume (PVR), and rates of peri-operative and late complications.

[Endoscopic therapy combined antegrade percutaneous approach and retrograde transurethral approach for ureteral obstruction after kidney transplantation].

Objective: To evaluate the method and efficacy of endoscopic therapy combined with antegrade percutaneous approach and retrograde transurethral approach for ureteral obstruction after kidney transplantation.

Methods: Eight cases were analyzed retrospectively who received endoscopic therapy combined with antegrade percutaneous approach and retrograde transurethral approach when they had been diagnosed with ureteral obstruction in the transplant kidney from February 2007 to March 2013 in Department of Urology, Peking University Third Hospital. The cases included three males and five females, with the average age being 44 years (30-64 years).

Marginal living donor in kidney transplantation: experience in a Chinese single center.

Background: Living donor kidney transplantation is becoming popular in China, whereas, in clinical situations, some kidney donors may be sub-optimal, namely marginal living donor. The present study aimed to evaluate the safety and efficacy of marginal living donor kidney transplantation in a Chinese single center.

Methods: Between January 2001 and December 2009, 888 kidney transplantations were performed in our center; 149 were living donor kidney transplantations.

[Laparoscopic nephron-sparing surgery for treatment of complex cystic renal lesions].

Objective: To evaluate the feasibility, efficacy and safety of laparoscopic partial nephrectomy for complex renal cystic lesions.

Methods: A retrospective cohort study was conducted on the clinical data of 27 patients with complex renal cystic lesions treated by laparoscopic partial nephrectomy from May 2008 to April 2011 in Peking University Third Hospital. According to the Bosniak classification, 7 cases were lesions of grade IIF, 11 of grade III, and 9 of grade IV.

[Joint therapy of native upper tract transitional cell carcinoma ipsilateral to a transplanted kidney by retroperitoneoscopic nephroureterectomy combined with a midline lower abdominal transperitoneal excision].

Objective: To present the preliminary experience of the operative procedure and clinical outcomes of retroperitoneal laparoscopic nephroureterectomy (RPLNU) with a midline lower abdominal transperitoneal incision for native upper urinary tract transitional cell carcinoma (UUT-TCC) ipsilateral to a transplanted kidney.

Methods: In the study, 15 renal recipients with native UUT-TCC ipsilateral to a transplanted kidney were operated on with RPLNU via a midline lower abdominal transperitoneal incision between November 2005 and January 2009. Retroperitoneal laparoscopic nephrectomy was performed first and followed by cystoscopic excision of ipsilateral ureteral orifice with bladder cuff.

[Postoperative urinary continence and learning curve after laparoscopic radical prostatectomy].

Objective: To evaluate urinary continence outcomes after laparoscopic radical prostatectomy (LRP), and explore the learning curve for continence.

Methods: Between May 2006 and May 2011, 200 consecutive patients with clinically localized prostate cancer underwent LRP in Peking University Third Hospital, of whom 160 were performed by a single surgeon and followed up successfully. The average age was (71.

[Efficacy and safety of transumbilical single-port laparoscopic radical nephrectomy].

Objective: To evaluate the efficacy and safety of transumbilical single-port laparoscopic radical nephrectomy.

Methods: The clinical data of laparoscopic radical nephrectomy performed from June 2010 to October 2010 in Peking University Third Hospital were analyzed retrospectively. In the study, 10 patients underwent transumbilical single-port laparoscopic radical nephrectomy (LESS) and 15 received retroperitoneal laparoscopic radical nephrectomy.

[Protective effect of heat shock protein 70 and magnesium sulfate supplementation on renal ischemia reperfusion injury].

Objective: To investigate whether there is a protective mechanism in exogenous magnesium ions supplement in renal ischemia reperfusion injury(IRI ), and to study the expression of heat shock protein 70 (HSP70) and HSP70-mRNA in the reperfusion injury.

Methods: A total of 90 male Japanese white rabbits (1.8-2.

Correlation between coagulation function, tumor stage and metastasis in patients with renal cell carcinoma: a retrospective study.

Background: The coagulation function in carcinoma patients is abnormal, but in renal cell carcinoma the extent and relationships of coagulation function remain unclear. This study retrospectively investigated the relationships between coagulation function, clinical stage and metastasis in patients with renal cell carcinoma.

Methods: A total of 350 consecutive patients admitted to our Urology Department from 2004 to 2010 were diagnosed with renal cell carcinoma by histopathologic examination and were included in this study.

[Improve recovery of urinary continence following laparoscopic radical prostatectomy: a clinical report of 51 cases].

Objective: To present the clinical results of 51 patients of clinically localized prostate cancer treated by laparoscopic radical prostatectomy, especially recovery of urinary continence. To analysis how to improve recovery of urinary continence.

Methods: From February 2004 to March 2008, we performed LRP on 51 patients.
