Inguinal incision as a successful route to extract the kidney during laparoscopic retroperitoneal live-donor nephrectomy.

Objectives: We sought to evaluate the advantages of an inguinal incision in extracting the kidney during retroperitoneal laparoscopic live-donor nephrectomy.

Materials And Methods: From May 2008 to June 2011, fifty-eight cases of retroperitoneal live-donor nephrectomy were performed at our hospital; all data were analyzed retrospectively. All donors were grouped in a test group (n=32, inguinal incision) or a control group (n=26, lumbar incision) according to the selected graft retrieval incision.

Transperitoneal laparoscopic nephroureterectomy for native upper tract urothelial carcinoma in renal transplant recipients.

Purpose: To analyze the safety and clinical outcome of laparoscopic nephroureterectomy (LNUT) for native upper tract urothelial carcinoma (UC) in renal transplant (RT) recipients.

Methods: We conducted a retrospective analysis of 956 RT recipients from January 2003 to December 2010 to evaluate the benefit of LNUT for patients who were diagnosed with de novo UC after renal transplantation.

Results: Women predominated (10/11, 91 %) in the 11 patients with upper tract UC who underwent LNUT.

Deep sequencing analysis of small non-coding RNAs reveals the diversity of microRNAs and piRNAs in the human epididymis.

The epididymis plays a crucial role in regulating the development of sperm motility and fertilizing capacity. Small non-coding RNAs (sncRNAs), especially microRNAs (miRNAs), can participate in the regulation of various physiological pathways. However, their abundance and whether they are involved in the regulation of gene expression in the human epididymis are unknown.

Inguinal oblique incision as an alternative route to extract the kidney during laparoscopic donor nephrectomy.

Objectives: Evaluate the advantages of inguinal oblique incision in extracting the kidney during laparoscopic donor nephrectomy.

Materials And Methods: From April 2005 to June 2009, sixty-seven cases of transperitoneal laparoscopic live-donor nephrectomies were performed at our hospital, all data were analyzed retrospectively. All donors were grouped as a test group (n=37, inguinal oblique incision) and a control group (n=30, paramidline or subcostal incision) according to graft retrieval incision selection.

Mapping of the human testicular proteome and its relationship with that of the epididymis and spermatozoa.

The testis produces male gametes in the germinal epithelium through the development of spermatogonia and spermatocytes into spermatids and immature spermatozoa with the support of Sertoli cells. The flow of spermatozoa into the epididymis is aided by testicular secretions. In the epididymal lumen, spermatozoa and testicular secretions combine with epididymal secretions that promote sperm maturation and storage.

Systematic mapping and functional analysis of a family of human epididymal secretory sperm-located proteins.

The mammalian spermatozoon has many cellular compartments, such as head and tail, permitting it to interact with the female reproductive tract and fertilize the egg. It acquires this fertilizing potential during transit through the epididymis, which secretes proteins that coat different sperm domains. Optimal levels of these proteins provide the spermatozoon with its ability to move to, bind to, fuse with, and penetrate the egg; otherwise male infertility results.

Transcriptome analysis of a cDNA library from adult human epididymis.

Mammalian Gene Collection (MGC) verified over 9,000 human full-ORF genes and FLJ Program reported 21,243 cDNAs of which 14,409 were unique ones and 5,416 seemed to be protein-coding. The pity is that epididymis cDNA library was missing in their sequencing target list. Epididymis is a very important male accessory sex organ for sperm maturation and storage.
