For instance, Radiotherapy of cervical cancer can cause ureteric stricture in 2.2% of patients at 10 years. [3] Radiotherapy had been identified as a modality of treatment of several cancers in the pelvis and the abdomen which may lead to ureteric stricture formation among other urological adverse effects too such as radiation induced cystitis.
This balloon is inflated with pure contrast agent via the pusher and remains in situ in the ureter to keep the previous treated stricture dilated while the expanded urothelium heals. Urine can drain through the central channel of this catheter.
Bladder outlet obstruction is included in the spectrum of congenital anomalies of the kidney and urinary tract (CAKUT). CAKUT is the most common cause of birth defects, occurring in 1 out of 1000 live births, and accounts for approximately half of all cases of chronic kidney disease and end-stage renal disease in children.

Renal colic, also known as ureteric colic, is a type of abdominal pain commonly caused by obstruction of ureter from dislodged kidney stones. The most frequent site of obstruction is the vesico-ureteric junction (VUJ), the narrowest point of the upper urinary tract .
Other patients may develop a shock-like condition and may require admission to a hospital. Serious complications of untreated urinary retention include bladder damage and chronic kidney failure. [4] Urinary retention is a disorder treated in a hospital, and the quicker one seeks treatment, the fewer the complications. [citation needed]
The prognosis of hydronephrosis is extremely variable and depends on the condition leading to hydronephrosis, whether one (unilateral) or both (bilateral) kidneys are affected, the pre-existing kidney function, the duration of hydronephrosis (acute or chronic), and whether hydronephrosis occurred in developing or mature kidneys. [citation needed]
Mean follow-up was 6.5 years. Complications include common ureteral narrowing (one patient); subsequent kidney removal, or nephrectomy (one patient); recurrence of disease with ureteral obstruction (one patient); and disease progression in a case of inflammation of blood vessels, or vasculitis (one patient).
A ureteric balloon catheter is a balloon catheter intended for treating strictures of the ureter. In fact it is a double J stent on which a balloon is mounted. It is connected to a delivery device (pusher) to introduce it from the bladder into the ureter. The system comprises a non-return valve device, and a pusher with a stylet and two ports.
