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 .
Urinary tract obstruction is a urologic disease consisting of a decrease in the free passage of urine through one or both ureters and/or the urethra. It is a cause of urinary retention. Complete obstruction of the urinary tract requires prompt treatment for renal preservation. [1]
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]
Ureter cancer rarely causes problems in the early stages, but as the cancer progresses, there are often side effects. [5] Symptoms of ureteral cancer may include "blood in the urine (); diminished urine stream and straining to void (caused by urethral stricture); frequent urination and increased nighttime urination (); hardening of tissue in the perineum, labia, or penis; itching; incontinence ...
Hydronephrosis describes hydrostatic dilation of the renal pelvis and calyces as a result of obstruction to urine flow downstream. Alternatively, hydroureter describes the dilation of the ureter, and hydronephroureter describes the dilation of the entire upper urinary tract (both the renal pelvicalyceal system and the ureter).
