PKUFH: Pure Intracorporeal Robotic Autotransplantation Overcomes Long-Segment Ureteral Defect
🩸 Diagnostic Dilemma
🔹 Recently followed a highly challenging upper urinary tract reconstruction case managed by Dr. Xuesong Li's team at Peking University First Hospital (PKUFH).
🔹 The 58-year-old male patient was diagnosed with the rare MASTUMP syndrome, presenting with a 7 to 8 cm long-segment ureteral defect with multiple annular strictures and polyps.
🔹 Facing such an extensive defect, conventional repair pathways typically involve bowel interposition or traditional open renal autotransplantation.
💡 Surgical Strategy
🔹 Bowel interposition carries a high risk of metabolic complications from urine absorption and enteric fistulas, while open autotransplantation is highly traumatic.
🔹 After rigorous evaluation, Dr. Li's team opted for an exceptionally demanding approach: pure intracorporeal robotic-assisted renal autotransplantation.
🔹 This decision completely avoided the risks of bowel substitution, perfectly preserved the anti-reflux mechanism of the intramural ureter, and minimized surgical trauma.
⚙️ Surgical Nuances
🔹 As demonstrated in the attached imaging and surgical records, the entire procedure demanded extreme robotic precision.
🔹 The first phase involved mobilizing the affected kidney and resecting the diseased ureter in a lateral decubitus position, followed immediately by intracorporeal cold perfusion upon vessel transection, achieving an astounding warm ischemia time of just 2 minutes and 8 seconds.
🔹 In the second phase, the patient was repositioned supine, and under continuous cold perfusion, the robotic system was utilized to execute precise anastomoses of the kidney to the ipsilateral external iliac vessels, directly connecting the renal pelvis to the healthy distal ureter.
🔬 Clinical Pearls & Outcomes
🔹 Intraoperative ultrasound confirmed excellent blood perfusion as the transplanted kidney rapidly regained a pink hue upon clamp removal.
🔹 The patient had a remarkably smooth postoperative recovery with stable renal function metrics, achieving a perfect reconstruction of physiological voiding.
🔹 This case profoundly demonstrates the ultimate minimally invasive decision-making capabilities of top-tier Chinese urology teams in complex anatomical reconstructions.
