We retrospectively reviewed our experience in performing endoscopic extraperitoneal radical prostatectomy (EERPE) and totally extraperitoneal (TEP) hernia repair in one procedure to evaluate its feasibility and safety. Based on our experience of 70 laparoscopic radical prostatectomies, a total of 60 patients underwent EERPE. Eight of these had 10 hernias repaired with Prolene mesh. The median total operating time for EERPE was 165 minutes. Mesh placement required an additional 15 minutes for a unilateral hernia and 25 minutes for bilateral hernias. The conversion rate and the reoperation rate were 0%. The median duration of vesical catheterization was 8.3 days. One patient required a blood transfusion. The most common minor complications, occurring in eight patients, were edema and hematoma of the penis. No wound infection occurred. The only major complication was a deep venous thrombosis in one patient. No additional complications developed in the hernioplasty group. We conclude that the extraperitoneal approach for radical prostatectomy allows concomitant inguinal hernia repair with a low morbidity rate and within an acceptable operating time.

We report the presence of KIT variants in granulosa and thecal cells of the follicle and endothelial and steroidogenic cells of the corpus luteum. Transcripts of both full-length splice variants, KIT and KITA, were ubiquitously detected in all cell types, in contrast to transcripts for truncated KIT. RT-PCR with exon-intron-specific primers suggested that KIT transcripts retained intron sequences. We used domain-specific KIT antibodies to identify truncated KIT proteins in cell conditioned media and lysates. These proteins represented soluble KIT and a so far disregarded intracellular KIT fragment, and were ubiquitously present. In contrast, glycosylated variants of full-length KIT were predominantly detected in thecal and endothelial cells. All KIT variants were encountered again in COS-7 cells transfected with a vector containing KITA. Phorbol 12-myristate-13-acetate treatment induced levels of truncated KITs, and this effect was repressed by the metalloproteinase inhibitor TAPI-1. Our findings show that ectodomain cleavage of full-length KIT generates an intracellular KIT. Our experiments suggest that replenishing full-length KIT differs among various ovarian cell types.
