Comparative Study
Laparoscopic renal ablation: an in vitro comparison of currently available electrical tissue morcellators.
Morcellation with the Cook high-speed electrical laparoscopic (HSEL) morcellator in an impermeable nylon/plastic sack (LapSac) has remained unchanged since its inception nearly one decade ago. Sack deployment and specimen entrapment remain relatively difficult, and morcellation with this device is expensive and relatively slow. As such, in an effort to facilitate specimen entrapment and morcellation, we adapted two currently available electrical morcellators (the Steiner gynecologic morcellator and the electrical prostate morcellator [EPM]) for renal morcellation and compared them with the HSEL morcellator. ⋯ Renal morcellation with all three morcellators is feasible. The Steiner morcellator combined with an Endocatch resulted in more rapid morcellation and larger morcellation products.

Multicenter Study Clinical Trial
Pentosan polysulfate therapy for chronic nonbacterial prostatitis (chronic pelvic pain syndrome category IIIA): a prospective multicenter clinical trial.
Chronic nonbacterial prostatitis/chronic pelvic pain syndrome (CPPS) has clinical and perhaps etiologic characteristics similar to interstitial cystitis. Pentosan polysulfate sodium (PPS), an oral medication indicated for the treatment of interstitial cystitis, has shown moderate benefit in reducing chronic pelvic pain and voiding symptoms in patients with interstitial cystitis. We undertook a prospective open-label, multicenter Phase II pilot study to examine the potential efficacy of PPS in the treatment of CPPS in men, using outcome tools validated for CPPS in men. ⋯ PPS is well tolerated and appears to have efficacy in reducing the severity and frequency of general symptoms, reducing specific pain symptoms, and improving the quality of life in many male patients with CPPS. The results of this study justify the initiation of a randomized controlled trial comparing the safety and efficacy of PPS to placebo.

An atraumatic anatomic technique for separation of the pediatric hernia sac from the spermatic cord.
A detailed photographically illustrated anatomic technique for the sequential dissection of the pediatric hernia sac from the spermatic cord has not been described. An illustrated technique to atraumatically dissect the hernia sac in a systematic fashion is therefore presented.
