What is a ureteroneocystostomy?

A ureteroneocystostomy is a surgical procedure that involves the reimplantation of the ureters into a newly constructed bladder. This procedure is often performed in cases where the bladder has been removed or significantly altered, such as in bladder cancer patients, or when addressing certain congenital anomalies.

During this operation, the ureters, which are the tubes that carry urine from the kidneys to the bladder, are surgically connected to a neobladder (a new bladder created using a section of the intestine). This allows urine to flow from the kidneys through the ureters, directly into the neobladder, thus restoring urinary function. The technique is critical in ensuring that urine can be stored and excreted properly after the usual bladder structure is compromised.

By understanding the context and purpose of this procedure, one can appreciate its significance in urology and surgical interventions. Other options relate to different surgical procedures that do not align with the definition or purpose of ureteroneocystostomy, emphasizing the importance of accurately delineating between various surgical techniques.
