Summary
This study details a new surgical technique for creating an artificial rectal urinary bladder, reducing risks of urinary peritonitis and pyelonephritis. Most patients showed recovery of upper urinary tract function within months.
Area of Science:
- Urology
- Surgical Technique Development
Context:
- Developing methods for urinary diversion is crucial for managing bladder dysfunction.
- Artificial rectal urinary bladders offer an alternative to traditional urinary diversion methods.
Purpose:
- To present a stepwise development and evaluation of a technique for urine derivation into an artificial rectal urinary bladder.
- To assess the safety and efficacy of this novel surgical approach.
Summary:
- The technique involves creating an artificial rectal urinary bladder by ligating the superior rectal artery and vein, and performing ureterorectal anastomosis.
- Key modifications include extra-abdominal rectal stump placement and preserving sigmoid colon, minimizing surgical trauma and urine resorption.
- Comparative evaluation of three technique modifications concluded that this method reduces urinary peritonitis and ascending pyelonephritis.
Impact:
- The artificial rectal urinary bladder technique minimizes risks of urinary peritonitis and ascending pyelonephritis.
- X-ray and radionuclide studies show upper urinary tract recovery in 75% of patients within 3-4 months.
- Renal function parameters like glomerular filtration and tubular reabsorption returned to preoperative levels post-surgery.
