Pioglitazone Enhances Survival and Regeneration of Pelvic Ganglion Neurons After Cavernosal Nerve Injury.

Objective: To investigate the effects of pioglitazone on pelvic ganglion neurons in a rat model of bilateral cavernosal nerve crush injury (BCNI), thereby elucidating the actions of pioglitazone in preventing post-prostatectomy neurogenic erectile dysfunction.

Methods: Sprague-Dawley rats aged 12 weeks were divided into four groups: (a) sham procedure, (b) BCNI, (c) BCNI + postsurgical pioglitazone, and (d) BCNI + pre and postsurgical pioglitazone (preventive therapy). Preoperative injection of Fluoro-Gold (FG) fluorescent tracer into the cavernosal tissue was performed for retrograde labeling of pelvic ganglion cells.

A Rationale to Use Bladder Boari Flap Reconstruction for Late Kidney Transplant Ureteral Strictures.

Objective: To evaluate the efficacy of Boari flap reconstruction (BFR) in the management of late-onset transplant ureteral strictures (TUS).

Methods: Between March 2007 and March 2014, there were 730 patients who underwent kidney transplant (KTx) at our institution. We identified 16 patients with TUS, occurring more than 60 days after KTx.

Avanafil for erectile dysfunction in elderly and younger adults: differential pharmacology and clinical utility.

The treatment modalities of erectile dysfunction range from oral pharmacotherapy to intracavernosal injections, intraurethral pellets, vacuum erectile devices, and the surgical option of penile prosthesis insertion. Oral phosphodiesterase 5 inhibitors still remain the preferred treatment for patients since they are the least invasive, not to mention that they can be prescribed by non-urologists. Due to these factors, there has been development of newer drugs with fewer side effects.

Double haploidentical hematopoietic stem cell transplantation results in successful engraftment of bone marrow from both donors without graft-versus-host or graft-versus-graft effects.

We established double-haploidentical (DH) hematopoietic stem cell transplantation (HSCT) murine models to explore competitive engraftment, graft-versus-graft effect and graft-versus-host disease (GVHD). T cell-depleted (TCD) bone marrow (BM) cells from B6SJF1 (donor 1 [D1]) and B6D2F1 (donor 2 [D2]) mice achieved >90% donor engraftment when transplanted into B6CBAF1 mice. B6CBAF1 recipients survived without evidence of GVHD when undergoing HSCT with TCD-BM from 2 haploidentical donors, D1 and D2.
