Case report: a 33-year-old man with recurrent ureteropelvic junction obstruction


Introduction: Ureteropelvic Junction Obstruction (UPJO) is the obstruction of upper urinary tract, present in fetal life until adulthood. Congenital UPJO mostly results from an intrinsic process with dilatation of renal collecting system. Acquired UPJO in adulthood may present without dilatation of renal collecting system, correlated with urolithiasis, infection, postoperative peripyelo-inflammatory fibrotic complication, and urothelial malignancy. In the past, Pyeloplasty, classic dismembered (Anderson-Hynes) or laparoscopic, is the gold standard treatment. In this study we would like to report and discuss comprehensive etiologies, diagnostic, and its treatment based from real case.

Case Presentation: We report case: a 33-year-old Indonesian man with left flank colic pain (VAS:8/10), nausea, and hematuria that did not disappear with medication. He had stone history in right proximal ureter with hydronephrosis and hydroureter, Ureterorenoscopy had been performed two years ago. Other vital signs and hemodynamics were stable. Abdominal USG demonstrated bilateral hydronephrosis and hydroureter. Abdominal X-Ray showed right ureter stone. Right-Left Ureterorenoscopy + Double-J-Stent were performed. The diagnosis was Bilateral Nephrolithiasis, Stenosis, and Proximal Ureter Obstruction leading to Recurrent UPJO. Three months later there was still pain, the patient was undergone Cystoscopy + URS + Laser Endopyelotomy + DJ-Stent Replacement (from 6 to 7 Fr). One month later, DJ-stents were removed but the stenotic ureter remained so Laparoscopic End-to-End Proximal Ureter Anastomosis Resection and DJ-stent Insertion were finally performed. Patient’s complaints were slightly reduced.

Conclusion: The Recurrent UPJO cause inadequate urinary flow leading to renal impairment. Clinical signs, symptoms, etiologies, and diagnostic imaging have significant role in determining the diagnosis. Early surgical intervention is the definitive treatment to reduce renal damage and its complications. Further researches to establish the causes, clinical manifestations, diagnostic imagings, and alternative treatments of UPJO are highly expected.
