What surgical intervention may be necessary for severe mechanical obstructions?

Severe mechanical obstructions in the urinary tract often require a surgical intervention to relieve the blockage and restore proper urinary flow. Prostatectomy, which involves the surgical removal of the prostate gland, is particularly relevant in cases where an enlarged prostate (benign prostatic hyperplasia) contributes to urinary obstruction in males. This intervention can significantly alleviate symptoms such as difficulty urinating or urinary retention caused by the mechanical blockage.

Other options may be valuable in certain contexts but do not specifically address severe mechanical obstruction directly. Cystoscopy is a diagnostic procedure that allows visualization of the bladder and urethra, but it does not resolve obstructions. Nephrectomy, the removal of a kidney, may be warranted in cases of significant kidney disease or damage but does not typically treat urinary obstruction per se. Hydrodilatation refers to the process of distending an area of the bladder with fluid, which may help in some cases, but it is not commonly a direct surgical intervention for mechanical obstructions. Prostatectomy stands out as a critical surgical solution for addressing severe obstruction due to prostate enlargement.
