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.

[Treatment of penile strangulation and sexual psychological analysis of the patients].

Objective: To find the best treatment of penile strangulation and to analyze the sexual psychological factors of the patients.

Methods: We retrospectively analyzed the experiences in removing foreign objects around the penis in 21 patients aged 19 - 61 years with the strangulation time varying from 10 hours to 4 days. The objects were mostly made of metal or plastics.

[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).

[Pelvic vas deferens abscess: a case report and review of the literature].

Objective: To investigate the clinical characteristics, diagnosis, misdiagnosis and treatment of pelvic vas deferens abscess.

Methods: The clinical data of one case of pelvic vas deferens abscess were reported and the relevant literature was reviewed.

Results: The patient underwent incision and drainage of pelvic vas deferens abscess.

[Retroperitoneoscopic dismembered pyeloplasty in children].

Objective: To evaluate the technique and the clinical efficacy of Retroperitoneoscopic dismembered pyeloplasty in children.

Methods: Retroperitoneoscopic dismembered pyeloplasty was performed on 17 patients of pediatric ureteropelvic junction (UPJ) obstruction, age ranging from 3 - 10 years. All patients had radiographic evidence of obstruction with signs, symptoms or deterioration of renal function.

[Living animal models of the medical shock wave].

This article reviews the methods, notes and evaluation of the living animal models of the medical shock wave, including directly shocked animal models, surgical implantation of stones into animal kidney models, implantation of tumor cells into animal models and animal bone models. The living animal models play an important role in studying the medical shock wave.
