Ileal trigonal urinary diversion: 5-year followup evaluation

Area of Science:

• Urology
• Nephrology
• Surgical Innovation

Background:

• Neurogenic bladder dysfunction poses risks to upper urinary tract health.
• Ileal conduit urinary diversion is a common surgical approach.
• Protecting renal function is a primary goal in managing neurogenic bladder.

Purpose of the Study:

• To evaluate the long-term efficacy of anastomosing the intact vesical trigone to an isolated ileal conduit.
• To assess the impact of this technique on upper tract deterioration in patients with neurogenic bladder.
• To determine the incidence of pyelonephritis, hydronephrosis, renal stones, and reflux.

Main Methods:

• Surgical procedure: Anastomosis of intact vesical trigone to isolated ileal conduit.
• Patient cohort: 24 patients with neurogenic bladder dysfunction.
• Follow-up duration: Primarily 5 years, assessing upper tract status.

Main Results:

• No pyelographic evidence of upper tract deterioration observed in any patient.
• Zero episodes of pyelonephritis or hydronephrosis reported.
• No renal stones detected; only 4 out of 46 renal units showed reflux.

Conclusions:

• Anastomosing the intact vesical trigone to an isolated ileal conduit offers superior protection for the upper urinary tracts.
• This surgical technique demonstrates excellent outcomes in preventing complications associated with neurogenic bladder dysfunction.
• The findings suggest this method is highly effective in preserving renal health in affected patients.
