A nomogram predicting re-operation due to secondary hemorrhage after monopolar transurethral resection of prostate.

We aim to develop a nomogram to predict re-operation due to secondary hemorrhage after Monopolar transurethral resection of the prostate (M-TURP). We identified patients undergoing M-TURP at Peking University First Hospital from 2000 to 2013. Univariate and multivariate logistic regression models were developed to predict the occurrence re-operation due to secondary hemorrhage.

Suprapubic cystostomy versus nonsuprapubic cystostomy during monopolar transurethral resection of prostate: a propensity score-matched analysis.

We aim to reassess the safety of the monopolar transurethral resection of the prostate (M-TURP) without suprapubic cystostomy at our institution over the past decade. This retrospective study was conducted in patients who underwent M-TURP at Peking University First Hospital between 2003 and 2013. A total of 1680 patients who had undergone M-TURP were identified, including 539 patients in the noncystostomy group and 1141 patients in the cystostomy group.

Correlation of benign prostatic obstruction-related complications with clinical outcomes in patients after transurethral resection of the prostate.

We aim to investigate the correlation of benign prostatic obstruction (BPO)-related complications with clinical outcomes in patients after transurethral resection of the prostate in China. We reviewed the medical history of all patients who underwent surgery from 1992 to 2013. We assessed the preoperative clinical profile, clinical management, and operative complications.

[Expression of ZNRD1 protein in human renal cell carcinoma].

Objective: To investigate the expression of zinc ribbon domain-containing1 (ZNRD1) in human renal cell carcinoma and normal kidney tissues.

Methods: The expression of ZNRD1 protein was examined by immunohistochemical staining in 71 renal cell carcinomas and 24 samples of normal kidney tissue. The correlation between the expressions of ZNRD1 protein and clinicopathologic features was analyzed.

[Diagnosis and treatment of retroperitoneal fibrosis: report of 26 cases].

Objective: To evaluate and improve the diagnosis and surgical treatment of the retroperitoneal fibrosis (RPF).

Methods: The medical records of 26 patients with the RPF (21 men and 5 women with mean age 54 years) were analyzed retrospectively. They were been treated from January 1996 to May 2007.

[The effect of Yunnan Baiyao on reduction of intra-operative bleeding of the patients undergoing transurethral resection of prostate].

Objective: To investigate the effect of Yunnan Baiyao on reduction of intra-operative bleeding of the patients undergoing transurethral resection of prostate (TURP).

Methods: A randomized placebo-control double-blind multi-center trial was conducted. 203 patients with benign prostate hyperplasia (BPH), aged 50 - 80, who were to undergo TURP were randomly divided into 2 groups: Yunnan Baiyao group, given 500 mg Yunnan Baiyao four times daily since the third day before the operation for 3 days, and placebo group, given empty capsules for 3 days.

[Expression of nucleosomal binding protein 1 in normal prostate benign prostate hyperplasia, and prostate cancer and significance thereof].

Objective: To investigate the expression of nucleosomal binding protein 1 (NSBP1) in normal prostate (NP), benign prostate hyperplasia (BPH), and prostate cancer (PCa) and significance thereof.

Methods: Western blotting was used to detect the expression of NSBP1 in 10 specimens of NP from voluntary donors who died of accidents, and 15 specimens of PCa resected during operation. Immunohistochemistry was used to detect the NSBP1 expression in 19 specimens of NP resected during complete cystectomy from patients with bladder carcinoma, and 26 specimens of BPH and 40 specimens of PCa, all resected during operation.

[Prediction of the stage of patients with prostate cancer by the combination of serum prostate specific antigen and Gleason score].

Objective: To explore the method of predicting the stage of prostate cancer with serum prostate-specific antigen (PSA) and pathological grade.

Methods: One hundred and eighty-seven patients were studied retrospectively with prostate cancer diagnosed by systemic biopsy in our hospital. The rank correlation analysis, rank sum test and stepwise discriminant multivariate analysis were used to assess the correlation of serum PSA level, ratio of free PSA to total PSA (FPSA/TPSA ratio) with Gleason score (GS) and stage.

[Diagnosis and management of primary hyperparathyrodism with urolithiasis].

Objective: To investigate the diagnosis and management of primary hyperparathyroidism with urolithiasis.

Methods: The clinical data of 12 patients who were diagnosed with primary hyperparathyroidism with urolithiasis from January 1998 to June 2004 were analyzed retrospectively.

Results: Four male and five female patients were demonstrated pathologically as parathyroid adenoma, with a mean age of 45.

[Clinical analysis of 174 cases of primary ureteral carcinoma].

Objective: To analyse the clinicopathological features and discuss the diagnosis, therapy and prognosis of primary ureteral carcinoma.

Methods: One hundred and seventy four cases of primary ureteral carcinoma diagnosed pathologically between January 1971 and July 2002 in our institution were followed up and retrospectively studied.

Results: The incidence of primary ureteral carcinoma was increasing during the last 30 years.

[Prevention of postoperative recurrence of human bladder carcinoma by intravesical instillation of immunotoxin, a clinical study].

Objective: To observe the effects of intravesical instillation of immunotoxin (IT) on the prevention of recurrence of bladder carcinoma.

Methods: 128 patients with superficial bladder carcinoma or bladder carcinoma of T2 stage underwent operation, and then were randomly divided into 3 groups 2 - 3 weeks after operation to be instilled intravesically with solution of mitomycin (n = 53), Calmette-Guerin vaccine (n = 30), or IT (n = 45) once a week for 8 weeks and then once every month for 8 months respectively. Cystoscopy, blood routine examination, routine urine examination, and liver function test were conducted every 3 months.
