Summary
Conservative measures effectively treated urinary extravasation in three patients. Ureteral catheterization resolved stone-induced cases, while multidisciplinary treatment addressed bladder cancer obstruction.
Area of Science:
- Urology
- Nephrology
Background:
- Urinary extravasation, a condition of urine leakage, can arise from various causes including ureteral stones and malignancy.
- Prompt diagnosis and appropriate management are crucial for successful patient outcomes.
Observation:
- Three distinct cases of urinary extravasation were successfully managed.
- Two cases involved spontaneous peripelvic extravasation secondary to ureteral calculi.
- One case presented as spontaneous renal pelvis rupture with urinoma due to bladder cancer-induced ureteral obstruction.
Findings:
- Conservative management, including indwelling ureteral catheterization, led to spontaneous stone passage and resolution of extravasation in two patients.
- A multidisciplinary approach, incorporating intra-arterial chemotherapy, radiation, and hyperthermotherapy alongside percutaneous nephrostomy, successfully recanalized the ureter and resolved the urinoma in the cancer-related case.
- These findings highlight the efficacy of tailored treatment strategies for different etiologies of urinary extravasation.
Implications:
- Conservative measures and minimally invasive interventions can be highly effective for managing urinary extravasation.
- Multidisciplinary treatment protocols are essential for complex cases involving malignancy-related ureteral obstruction.
- Further research into optimal diagnostic and therapeutic pathways for urinary extravasation is warranted.
