Ileocecal conduit for temporary and permanent urinary diversion.

Area of Science:

• Urology
• Surgical Innovation
• Gastrointestinal Surgery

Background:

• Urinary diversion is crucial for managing reversible bladder disorders.
• Preventing reflux into the upper urinary tract is essential for renal preservation.
• Existing diversion techniques may have limitations in preventing reflux.

Purpose of the Study:

• To evaluate the efficacy of an ileocecal intestinal segment as a urinary diverting conduit.
• To assess the success of a modified ileocecal valve fundoplication in preventing reflux.
• To determine the impact on renal function and hydronephrosis in patients undergoing this diversion.

Main Methods:

• Utilized the ileocecal intestinal segment for urinary diversion in 6 patients.
• Employed a fundoplication technique on the ileocecal valve to create an antireflux mechanism.
• Conducted follow-up assessments including intravenous pyelography (IVP) and renal function studies.

Main Results:

• Achieved satisfactory colonic stomas and successful antireflux modification of the ileocecal valve.
• Observed resolution of pre-existing hydronephrosis and preservation of upper urinary tracts.
• Demonstrated successful reversal of diversion in one patient via cecocystoplasty with preserved renal function.

Conclusions:

• The ileocecal segment with an antireflux mechanism is a viable option for urinary diversion.
• This technique effectively prevents ileocecal and ureteral reflux, safeguarding renal function.
• The antireflux conduit is applicable to hydronephrotic collecting systems, offering significant functional advantages.
