Post traumatic ureteral defect brigded with ileal segment (Yang-Monti) for inferior ureterocalycostomy: a rare case report with review of literature

Abstract

Ureteric substitution using the Yang-Monti principle was reported as a modification of simple ileal ureter replacement. A patient underwent ileal ureteral substitution using a reconfigured ileal segment of Yang-Monti principle in our clinical centre. Authors report a case of a 41year old male involved in a homicidal stab injury with isolated renal pelvis injury underwent Thompson’s renal capsular flap repair. After 6 weeks, double J (DJ) stent was removed and following that patient developed urinoma. Percutaneous drain was placed to drain urinoma on emergency basis and again 6 Fr DJ stent was inserted but patient had recurrent fever and chills. On CECT evaluation authors noticed that DJ stent was outside the upper urinary tract. And then patient was re-explored where authors found 6 cm stricture of the proximal left ureter. A reconfigured small bowel tube was interposed between inferior calyx and proximal ureteral stumps. This technique offers certain distinct advantages. A short ileal segment is included with the consequent absence of metabolic complications. Yang-Monti Principle is a safer and efficient technique for clinical partial and complete ureteral defects with sustained, good, long-term results. Yang-Monti reconfigured tube seems to be promoted an equally efficient urine transport mechanism that persists unaltered for long periods if patients and potential risks could be well prepared.
