Comparative Study
Microparticulate ice slurry for renal hypothermia: laparoscopic partial nephrectomy in a porcine model.
Previously, we described the feasibility of renal hypothermia using microparticulate ice slurry during laparoscopy. In the present study, we compared surface cooling with the ice slurry versus near-frozen saline or warm ischemia (WI) during laparoscopic partial nephrectomy (LPN) in a porcine model. ⋯ Ice slurry provides superior renal cooling compared with near-frozen saline during LPN without associated core hypothermia.

To present a simple technique for the repair of a ruptured testis after blunt trauma when extruded but viable testicular tissue prevents closure of the testicular capsule during surgical exploration. Preservation of viable testicular tissue is important because the risk of impaired fertility and hormone function is minimized. ⋯ This technique avoids the loss of extruded but viable testicular tissue and may reduce the risk of impaired fertility and hormone function, without compromising the goals of scrotal exploration.

To report the first series of laparoendoscopic single-site surgery for radical cystectomy and bilateral pelvic lymph node dissection. The development of laparoendoscopic single-site surgery and its application to urothelial malignancy has not been previously evaluated. ⋯ Laparoendoscopic single-site surgery for radical cystectomy and bilateral pelvic lymph node dissection is feasible and safe for select patients. Adequate lymph node dissection was possible through a single multichannel port. The long-term oncologic evaluation of these patients awaits; however, the preliminary outcomes have been promising.

To investigate the distribution of dichotomizing afferents supplying both the prostate and urinary bladder, and to discern the effects of noxious stimulation of the prostate on urinary bladder function in rats. ⋯ These findings suggest that bladder-prostate convergent DRG neurons may play a role in bladder-prostate cross-sensitization after prostatitis. This study also provided neuronal anatomical evidence for voiding dysfunction associated with chronic prostatitis/chronic pelvic pain syndrome.

A comprehensive literature study was conducted to evaluate the levels of evidence (LEs) in publications on the diagnosis and staging of penile cancer. Recommendations from the available evidence were formulated and discussed by the full panel of the International Consultation on Penile Cancer in November 2008. The final grades of recommendation (GRs) were assigned according to the LE of the relevant publications. ⋯ Adjuvant radiotherapy after complete ILND can be considered in patients with multiple or large inguinal metastases or ENE (GR C). Adjuvant chemotherapy after complete ILND can be used instead of radiotherapy in patients with >/=2 inguinal metastases, large nodes, ENE, or pelvic metastases (GR C). Follow-up should be individualized according to the histopathologic features and the management chosen for the primary tumor and inguinal nodes (GR B).
