Hydronephrosis is usually caused by urinary tract obstruction that causes poor urine drainage in both kidneys, resulting in the accumulation of urine in the urinary tracts of both kidneys, which is manifested by enlargement of the urinary ducts in both kidneys.
Urinary tract obstruction leading to hydronephrosis is common in the lower urinary tract, such as urethral strictures, chronic urinary retention associated with prostatic hyperplasia, chronic urinary retention of the neurogenic bladder, compression of the urethra, bladder, or bilateral ureters by pelvic lipodia, and bilateral ureteral orifice by glandular cystitis or bladder tumors. Bilateral upper urinary tract obstruction can also lead to hydronephrosis due to bilateral upper urinary tract obstruction, such as biureteral stones, retroperitoneal fibrosis, bilateral congenital dysplasia, and ureteropelvic junction stenosis.
The symptoms of hydronephrosis are similar to those of hydronephrosis on one side, such as back pain, abdominal mass, and some people may experience decreased urine output and impaired kidney function. Other manifestations are associated with the primary disorder causing hydronephrosis. Imaging tests such as ultrasound, CT, MRI, and urography can help confirm the diagnosis of hydronephrosis.
Hydronephrosis is mainly carried out for **, such as idiopathic retroperitoneal fibrosis leading to hydronephrosis and requires immunological drugs**;Minimally invasive surgery to remove double ureteral stones;Minimally invasive prostatectomy surgery is performed for prostatic hyperplasia. Sometimes drainage of hydronephrosis is needed, including placement of ureteral stents or nephrostomy.
