How is ureterocele treated?

A ureterocele is a cystic dilation of the distal (terminal) portion of the ureter. During embryonic development, failure of the septum between the ureter and the urogenital sinus to resorb and regress leads to varying degrees of stenosis at the ureteral orifice. Alternatively, it may result from inherent weakness of the fibrous structures in the distal ureter or an abnormally long or tortuous intramural course of the ureter.

How Is a Ureterocele Treated?

The primary treatment principles for ureterocele include relieving urinary obstruction, preventing vesicoureteral reflux, and managing associated complications. Treatment strategies are individualized based on the size of the ureterocele, presence or absence of clinical symptoms, and the functional status of the affected kidney. Specific approaches include:

1. Small, simple ureteroceles without obstruction or reflux may be managed conservatively with close observation and no immediate intervention.

2. Large, simple ureteroceles at the ureteral orifice can be treated by surgical excision of the ureterocele combined with ureteral reimplantation into the bladder, or alternatively via transurethral endoscopic incision of the ureterocele.

3. In cases of ureterocele associated with a duplicated collecting system—specifically involving the upper pole ureter—management depends on renal function: if the upper pole kidney is nonfunctional, nephroureterectomy of the upper pole unit is indicated; if both upper and lower pole kidneys retain adequate function, ureterocele excision with ureteral reimplantation may be performed.

4. Ectopic ureteroceles are best managed by intravesical excision of the ureterocele followed by ureteral reimplantation into the bladder.

Can Ureterocele Be Prevented?

Ureterocele is generally not preventable, as it is a congenital anomaly. However, urinary tract infections (UTIs) associated with ureterocele can often be prevented using prophylactic antibiotics. The management of ureterocele depends on the timing of diagnosis and the severity of symptoms.

If prenatal ultrasound detects a ureterocele, physicians typically recommend a series of postnatal imaging studies to evaluate urinary tract anatomy and renal function. Based on the size of the ureterocele and its impact on renal function, clinicians may opt either for continued surveillance or initiation of treatment—the most common approach being conservative observation.
