Teapot ureterocystoplasty in posterior urethral valve and chronic kidney disease: a case report

BACKGROUND: Bladder augmentation is frequently required to manage poorly compliant, low-capacity bladders resulting from posterior urethral valves (PUV). While traditional enterocystoplasty techniques are limited by complications associated with bowel tissue use, ureterocystoplasty presents a favorable alternative in patients with concurrent megaureter. METHODS: We describe a novel teapot ureterocystoplasty technique that enhances ureteral vascular preservation by maintaining a 3 cm distal ureteral segment in its detubularized configuration. Postoperative outcomes demonstrated significant improvement, with cystographic bladder capacity increasing from 50 to 180 mL. Renal function stabilized following a transient creatinine elevation to 250 μmol/L. RESULTS AND CONCLUSION: At a 4.5-year follow-up, the patient continues to do well and has successfully avoided renal transplantation-an outcome commonly required for such pediatric cases.
