The results of the dermal and cadaveric pericardial grafts were comparable. The minimal preoperative preparation, decreased patient morbidity and pliability of cadaveric pericardium make it an attractive suitable graft substitute in the modified Horton-Devine procedure. Longer followup and larger patient series are needed to confirm the advantages of cadaveric pericardium.

OBJECTIVETo assess the feasibility and efficacy of commercially available fibrin tissue sealant as a haemostatic agent and collecting-system sealant during hand-assisted laparoscopic partial nephrectomy (LPN). PATIENTS AND METHODSFifteen consecutive patients underwent LPN for enhancing renal masses suspicious for renal cell carcinoma via a transperitoneal approach and with the use of a handassistance device. Monopolar electrocauterization and argon-beam coagulation were initially used to slow bleeding from the resection site. Through a laparoscopic applicator, Tisseel TM fibrin sealant (Baxter Inc., Deerfield, IL) was applied to the transected partial nephrectomy bed while the surgeon's hand maintained adequate compression and partial haemostasis. No further haemostatic measures were required in any patient; the patients were evaluated for acute and delayed bleeding or urinary extravasation. RESULTSIn all cases electrocauterization and argonbeam coagulation followed by the application of Tisseel was successful in obtaining strict haemostasis of the surgical bed, with no evidence of bleeding during or after surgery on immediate and extended follow-up. In addition, there was no evidence during or after surgery of any urinary leak. There were no immediate or delayed complications in any of the patients; a short-term outpatient follow-up (12-60 weeks) revealed no additional problems. CONCLUSIONSConventional haemostatic measures of electrocauteriztion and argon-beam coagulation combined with commercial fibrin sealant allows successful haemostasis during LPN. In addition to haemostatic properties, fibrin sealants appear to have sealing properties that may help to prevent complications of urinary leakage by helping to seal or close the small defects in the urinary collecting system. The use of this compound may facilitate the ability of the urological laparoscopist during LPN.

Peyronie's disease in men with satisfactory erectile function but with significant penile curvature is often treated with plaque incision or excision and grafting. The advantages and disadvantages of various grafting materials have long been debated. While artificial materials have been used, the inflammatory reaction from these grafts has produced poor results. Dermal, venous and tunica vaginalis grafts require additional operative time to harvest and their quality varies Packaged grafts of autologous materials provide a readily available, reliable and well-tolerated choice for penile reconstruction for Peyronie's disease. These grafting materials including cadavaric pericardium, mammalian intestinal serosal products and others are easily obtained and provide a resilient yet compliant graft choice that is easy to tailor and suture in place. Host reaction is minimal and the infection risk small.Results of Peyronie's plaque incision=excision and autologous grafting are presented and the surgical procedures employed are outlined. Excellent results can be expected in the hands of the experienced reconstructive surgeon.
