Prospective randomized comparison of transumbilical two-port laparoscopic and conventional laparoscopic varicocele ligation.

We have established a novel method named transumbilical two-port laparoscopic varicocele ligation (TTLVL) for varicocele, which is still needed to evaluate. In this study, 90 patients with left idiopathic symptomatic varicoceles of grades II-III according to the Dubin grading system were randomly assigned to TTLVL (n = 45) and conventional laparoscopic varicocele ligation (CLVL) (n = 45). The demographic, intraoperative, postoperative, and follow-up data were recorded and compared between the two groups.

Overexpression of FoxM1 is associated with tumor progression in patients with clear cell renal cell carcinoma.

Background: Fork head box M1 (FoxM1) is a proliferation-associated transcription factor essential for cell cycle progression. Numerous studies have documented that FoxM1 has multiple functions in tumorigenesis and its elevated levels are frequently associated with cancer progression. The present study was conducted to investigate the expression of FoxM1 and its prognostic significance in clear cell renal cell carcinoma (ccRCC).

[Sperm retrieval and the predictive parameter of non-obstructive azoospermia: a meta-analysis of literatures 1990 to 2008].

Objective: To investigate which sperm retrieval technique is suitable for the non-obstructive azoospermia (NOA) patient, and to identify the relevant predictive parameters.

Methods: Literatures on NOA patients who had undergone sperm retrieval and pathological examination of testis were identified from Cochrane Library, CNKI and Medline (1990 to 2008) and analyzed.

Results: Twenty-five articles were enrolled.
