Duplicate renal malformation is a congenital disease of the urinary system, with an incidence rate of 0.8%. Surgical treatment is suitable for symptomatic patients. Urinary fistula is one of the complications of heminephrectomy. Long-term urinary fistula has a great impact on patients' lives.
This article mainly reports on a 47-year-old man with duplication of kidney deformity, long urinary fistula after partial nephrectomy, and no improvement after conservative treatment. We have achieved positive results in the arterial embolization treatment of the residual renal artery, indicating that selective arterial embolization is a good way to treat urinary fistula after partial nephrectomy. It is worth noting that this patient violated the Weigert-Meyer law, which also gave us more consideration.
Renal artery embolization may be a simple and safe method to treat urinary fistula inefficacy with conservative treatment.
Core Tip: Urine leakage is one of the complications of heminephrectomy, and it leads to a serious decline in the patient’s quality of life. For patients who fail conservative treatment, they may also face the risk of reoperation. We successfully treated a patient with urine leakage after heminephrectomy through selective renal artery embolization. After 3 years of follow-up observation, the patient's renal function was normal and no urinary fistula recurred.
