[Intermittent hydronephrosis caused by ureteral polyp in childhood: report of a case]
1Department of Urology, Kanagawa Children's Medical Center.
Insights
A rare case of ureteral polyps caused intermittent hydronephrosis and flank pain in a 12-year-old boy. Surgical removal of the polyps led to a complete symptom resolution, highlighting effective treatment for this condition.
Area of Science:
- Pediatric Urology
- Nephrology
- Surgical Pathology
Background:
- Ureteral polyps are rare benign tumors that can cause urinary tract obstruction.
- Intermittent hydronephrosis and flank pain are potential symptoms of ureteral polyps, particularly in pediatric patients.
Observation:
- A 12-year-old boy presented with recurrent right flank pain and gross hematuria, leading to hospitalizations.
- Excretory urography (IVP) demonstrated intermittent hydronephrosis, with significant right renal pelvis dilation during symptomatic episodes.
Findings:
- Surgical exploration revealed four ureteral polyps during an Anderson-Hynes pyeloplasty.
- Pathological examination confirmed the presence of fibrous ureteral polyps.
- Partial ureterectomy with polyp excision resulted in complete symptom resolution at 3-month follow-up.
Implications:
- This case highlights ureteral polyps as a treatable cause of intermittent hydronephrosis in children.
- Prompt diagnosis and surgical intervention, such as partial ureterectomy, can effectively manage symptoms and prevent complications.
- Further research into the etiology and optimal management of pediatric ureteral polyps is warranted.
Abstract:
We report a case of ureteral polyp causing intermittent hydronephrosis in a 12-year-old boy. He was often hospitalized with episodes of right flank pain and gross hematuria. An excretory urogram (IVP) revealed mild hydronephrosis, but it showed a markedly dilated right renal pelvis during the attack. An Anderson-Hynes type pyeloplasty was done. At operation we found four ureteral polyps, and performed partial ureterectomy including polyps. Pathological examination showed fibrous ureteral polyps. He has reported no symptoms for 3 months after the operation.
