New York is described as the “Best City in the World.” It is an easy destination to get to from most anywhere and has almost everything to offer. While the PSRC has been held here previously, it has not been in New York since 1995 and this will mark the first time that Mount Sinai Medical Center will serve as the host institution. I first presented at the PSRC in Galveston, Texas in 1997 as a general surgery resident and have been an active member since. I believe the PSRC is the most important society of our specialty. The work performed by our member surgeons is at the forefront of healthcare as a whole. Our members are the brightest and most creative we have to offer and to that end, I have incredible respect. This year’s meeting will undoubtedly be exciting and provocative. I am fortunate to be able to plan the meeting with Dr. David Mathes who brings tremendous energy to our society. Unlike prior years, the entire program will be held at the brand new Conrad Hotel in Battery Park City, which overlooks the Hudson River, New York harbor, and the Statue of Liberty. Following the

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Background: Staple line reinforcement material has been demonstrated to raise the burst pres- sure threshold after linear intestinal stapling. Numerous bioprosthetic materials have been uti- lized in surgical practice. Porcine urinary bladder matrix (ACell, Inc.) is an extracellular matrix material derived from porcine bladder used to reinforce surgically repaired soft tissue, and facili- tate the body’s regenerative capacity. Objective: This study represents the first evaluation of uri- nary bladder matrix in gastrointestinal staple line reinforcement. Methods: Pathogen-free pigs underwent midline laparotomy under general anesthesia. Small intestinal division was performed with an endoscopic linear stapler. Nineteen intestinal divisions were performed with urinary bladder matrix staple line reinforcement, and twenty divisions were unreinforced. Staple lines were then subjected to burst pressure analysis by intraluminal infusion of dyed Krebs solution at an infusion rate of 20 ml·min−1 under manometric monitoring. Upon visible staple line extravasa- tion, intraluminal pressure was recorded. Results: Intestinal staple lines reinforced with urinary bladder matrix exhibited significantly higher burst pressure threshold (p < 0.05).

    UIJ UroToday International Journal® Percutaneous Dilatation of Non-malignant Ureteroenteric Anastomotic Strictures in Patients with Urinary Diversion After Cystectomy for Bladder Cancer: 7 Patients Sallami Satáa, Olfa Zrayer, Habiba Mizouni, Sami Ben Rhouma, Mohamed Hmidi, Mourad Gargaouri, Maher Chtourou Submitted June 18, 2012 - Accepted for Publication July 23, 2012 ABSTRACT Background: The management of ureterointestinal stricture in patients who have undergone urinary diversion can be challenging. Endourological techniques have been increasingly used in recent years for such strictures. Objectives: We report our experience and evaluate our results on balloon antegrade dilatations for benign ureteroenteric anastomotic strictures after total cystectomy and urinary diversion by ileal conduit. Patients and Methods: Between December 1990 and May 2009, 8 balloon dilatations were performed on 7 patients with a mean age of 56.6 years (range: 50 to 72) to treat ureterointestinal strictures. Strictures were dilated percutaneously via the antegrade approach under fluoroscopic control. A ureteral multi-hole catheter was left for 6 to 8 weeks. Success was defined as radiological resolution of obstruction and the ability to recover normal activity in the absence of flank pain, infection, or the need for ureteral stents or nephrostomy tubes. Results: The development of strictures occurred a mean of 4.5 months after urinary diversion. Eight renal units were treated (5 left, 3 right), including 1 bilateral procedure. There were 6 complete and 2 partial strictures. The operative time did not exceed 45 minutes. No major complications were encountered during or after these procedures. The overall success rate was 43%. Three patients required open reimplantation. Six of 7 patients showed satisfactory outcomes and 1 patient was lost to follow-up.

Waldron Veterinary Medical Sciences This study compared the effects of urinary diversion by tube cystostomy catheterization, urethral catheterization and tube cystostomy and urethral catheterization on healing urethral anastomoses in the canine urethra. Fifteen intact, mature males were divided into three groups of five dogs. Urodynamic studies were performed under halothane anesthesia preoperatively and at ten weeks postoperatively. Urethral anastomosis was performed in all dogs over a urethral catheter with 4-0 polyglyconate. Group U dogs (n=5) received transurethral catheters. Group C dogs (n=5) received tube cystostomy catheters, and Group B dogs (n=5 ) had both a transurethral catheter and a cystostomy tube placed. All dogs had catheters maintained with a closed urine collection system for seven days. Dogs were observed for ten weeks following surgery, and urinalysis and urine cultures were performed on weeks 1, 4, and 8. Preoperative evaluations were repeated ten weeks postoperatively just prior to termination of the study. Radiographic and histopathologic evaluation of the urethral specimen was performed.

  • Automated Uretero-Intestinal Anastomosis with Absorbable Staples
    Journal of Endourology Automated Uretero-Intestinal Anastomosis with Absorbable Staples Bollom M., Grosskopf V., Paulsen S., Theisen J. ABSTRACT Bladder cancer is the 5th most common cancer in the United States. When cancer cells invade the bladder muscle, surgical removal of the bladder, called radical cystectomy, is the desired treatment. A neobladder is formed out of a portion of intestine, and the ureters are currently attached via absorbable sutures. We have designed rigid absorbable staples comprised of 85:15 poly(lactide-co-glycolide) (PLGA) and a surgical anastomosis stapler to fire two concentric rings of six staples each. Degradation testing shows that the staples will retain strength for at least 20 days, long enough to promote healing of the tissue. Functional testing shows that the average grip strength of a single staple is 5.34 ± 1.5 N and 11.58 ± 2.28 N for a single suture stitch. Future testing will analyze the anastomosis strength of 12 staples fired using the circular stapler. INTRODUCTION According to the National Cancer Institute, bladder cancer is the 5th most common cancer in the United States. In 2012, there will be over 73,000 new cases reported in the United States and 15,000 people will die from bladder cancer1. When the tumors invade the bladder muscle, the desired treatment is radical cystectomy, surgical removal of the entire bladder2. Following removal of the bladder, a surgeon will commonly construct a new, internal neobladder using a portion of the intestine. The ureters are currently attached to the neobladder with absorbable sutures. This attachment must be watertight so urine does not leak into the abdominal cavity.
