Patients can also be treated with alpha blockers [7] in cases where the stone is located in the ureter. A 2019 review found three cases of renal colic were hydronephrosis caused by malpositioned menstrual cups pressing on a ureter. When the cups were removed, the symptoms disappeared. [8]
These advantages are especially apparent with stones greater than 10 mm (0.4 in) in diameter. However, because ureteroscopy of the upper ureter is much more challenging than ESWL, many urologists still prefer to use ESWL as a first-line treatment for stones of less than 10 mm, and ureteroscopy for those greater than 10 mm in diameter.

Hydronephrosis due to a kidney stone at the ureteral vesicular junction seen on CT scan. Prenatal diagnosis is possible, [9] and in fact, most cases in pediatric patients are incidentally detected by routine screening ultrasounds obtained during pregnancy. [10]
Kidney stones are becoming more common with time, and their incidence is believed to increase recently due to unhealthy diet habits. The passage of kidney stones into ureters might lead to their impaction and the development of local inflammatory process around the stone in addition to the obstruction of the ipsilateral kidney and build up of pressure manifested as hydronephrosis.
Ureteroscopy is an examination of the upper urinary tract, usually performed with a ureteroscope that is passed through the urethra and the bladder, and then directly into the ureter. [1] The procedure is useful in the diagnosis and treatment of disorders such as kidney stones and urothelial carcinoma of the upper urinary tract. [1]

A 2013 meta-analysis found LL can treat larger stones (> 2 cm) with good stone-free and complication rates. [ 5 ] Holmium laser lithotripsy had superior initial success and re-treatment rate compared to extracorporeal shock wave lithotripsy (ESWL) in a 2013 trial.
A retrograde pyelogram may be performed to find the cause of blood in the urine, or to locate the position of a stone or narrowing, tumour or clot, as an adjunct during the placement of ureteral stents. [13] It can also be used ureteroscopy, or to delineate renal anatomy in preparation for surgery.
