OBJECTIVES: The purpose of this study is to examine the feasibility of performing a laparoscopic @entity1494 and to assess the urodynamic characteristics of an autoaugmented bladder. METHODS: Laparoscopic @entity1494 was performed in 9 female @entity235 (20 to 30 kg). Following laparoscopic access to the peritoneal cavity, a midline @entity1494 was performed using the @entity17835 532 nm laser. This produced a large @entity1494 . Changes in bladder volume and compliance were quantified over a 3-month period of follow-up. RESULTS: Urodynamic evaluation demonstrated an increase in bladder capacity 6 weeks postoperatively in 8 of 9 @entity235 , with an average volume increase of 45%. Bladder compliance improved in 7 of 9 @entity235 with an average increase in compliance of 67%. Three months postoperatively, bladder capacity remained increased in 5 of 9 @entity235 , with an average increase in volume of only 5.3%. An improvement in compliance was sustained in 5 of 9 animals with an average increase of 13.9%. Laparoscopic exploration revealed grossly normal bladders with adhesions of omentum to the seromyotomy site in all @entity235 and the anterior abdominal wall in 2 of 9 @entity235 . Histologically, the seromyotomy site was devoid of muscle with an intact urothelium and a proliferation of loose connective tissue. CONCLUSIONS: The technique of laparoscopic @entity1494 can be performed easily in the @entity235 model. Although results at 6 weeks show significant improvement, the longer term, 3-month results were not statistically significant. This technique has the potential to offer a minimally invasive correction for @entity1 with low-capacity, high-pressure bladders that have failed pharmacologic treatment.
