[Complications of laparoscopic surgery: a 11-year single institute experience].

Objective: To analyze the complications of laparoscopic surgery for the past 11 years in the Urology Department of Peking Union Medical College Hospital.

Methods: The laparoscopic surgery of 5 386 cases from Jan. 2002 to Dec.

Open partial nephrectomy in solitary kidney with multiple renal cell carcinoma: a case report.

Renal cell carcinoma (RCC) in a solitary kidney presents a unique clinical challenge to urological surgeons. Partial nephrectomy (PN) or nephron-sparing surgery in this condition provides good oncological and renal functional outcomes with an acceptable complication rate. Long-term renal function remains stable in most patients with solitary kidneys after a reduction of more than 50% in renal mass.

[Clinical features of urological malignancies with paraneoplastic syndromes].

Objective: To investigate the clinical features of paraneoplastic syndromes (PNS) in patients with renal, prostate and bladder cancer and conduct a brief prognostic analysis.

Methods: From 2008 to 2010, 464 patients of renal cell carcinoma (RCC) confirmed by operation and pathology were reviewed retrospectively. And 562 cases of patients with prostate cancer and 647 with bladder cancer from 2005 to 2010 were also analyzed respectively.

[Diagnosis and treatment of primary pigmented nodular adrenocortical disease report of 4 cases].

Objective: To study the diagnosis and treatment of primary pigmented nodular adrenocortical disease (PPNAD).

Methods: The clinical data including symptom, endocrinal examination, surgical operation and prognosis of 4 cases of PPNAD hospitalized from 2000 to 2007 were analyzed respectively, relative literature were reviewed.

Results: 1 case received total adrenalectomy needed adrenocortical hormone postoperatively, 3 cases responded favorably to subtotal adrenalectomy and did not need adrenocortical hormone, however, 1 case was diagnosed of thyroid carcinoma 2 years after subtotal adrenalectomy.

[Occurrence, types, and therapies of malignant tumors in recipients of renal transplantation].

Objective: To investigate the types and therapies of malignancies in renal allograft recipients.

Methods: We retrospectively analyzed the occurrence, types, and therapies of malignancies in 498 renal allograft recipients who had received operations in Peking Union Medical College Hospital from May 1986 to October 2008.

Results: Among 498 renal allograft recipients, 18 patients (3.

[Analysis of protamine content in patients with asthenozoospermia].

Objective: To study the significance of the change of protamine content in the management of male infertility.

Methods: Sperm nuclear proteins extracted from 199 infertile patients were analyzed by polyacrylamide gel-electrophoresis and scanning microdensitometry.

Results: Forty-two (21%) cases of the total number had normal sperm nuclear proteins and 157 (79%) had aberrant ones, which mainly presented the interruption of HPRR and abnormality of P2 protamine.

[The evaluation of the diagnosis and treatment of 32 cases with ectopic ACTH syndrome].

Objective: To investigate and discuss the diagnosis and treatment of ectopic ACTH syndrome.

Methods: Clinical data of 32 cases of ectopic ACTH syndrome, recruited from January 1990 to April 2003 in our hospital, was analyzed.

Results: All of the 32 cases presented with clinical and biochemical evidences of Cushing's syndrome.

[Clinic analysis of repeat prostatectomy after transurethral prostatectomy for benign prostatic hyperplasia].

Objective: To analyze the incidence rate of repeat transurethral prostatectomy (TURP) and its probable causes after TURP for benign prostatic hyperplasia (BHP).

Methods: A retrospective study was conducted to summarize the cases who received repeat transurethral resection of prostate after TURP for benign prostatic hyperplasia in recent 20 years. The data were compared with the data of the cases who just received once TURP for BPH.

[Telomerase expression in various lesions of adrenal cortex].

Objective: To investigate the expression of telomerase in various lesions of adrenal cortex.

Methods: By autoradiography-based telomeric repeat amplification protocol, telomerase expression was detected in 36 samples of adrenocortical lesions, including 29 cases adrenocortical adenoma (8 Cushing's syndrome, 17 aldosteronism and 4 nonfunctional adenomas), 5 cases of hyperplasia of adrenal cortex (presented with Chushing' syndrome), 2 cases adrenocortical carcinoma, and 4 samples of normal adrenal cortex.

Results: Of the 40 samples, 2 cases of adrenocortical carcinomas had telomerase expression, and the others had no telomerase expression detected.
