Which surgical procedure is recommended for BPH when the prostate is smaller than 30g?

The best choice for managing benign prostatic hyperplasia (BPH) when the prostate is smaller than 30 grams is the transurethral incision of the prostate (TUIP). This procedure is particularly effective for smaller prostates as it offers several advantages over other surgical options.

TUIP involves making small incisions in the prostate rather than removing tissue, which can lead to a quicker recovery, fewer complications, and less impact on sexual function. The incisions help to relieve urinary obstruction caused by the enlarged prostate by widening the urethra, improving urinary flow without the necessity of removing any significant amount of prostate tissue.

In cases where the prostate size is greater than 30 grams, other procedures such as transurethral resection of the prostate (TURP) or open prostatectomy might be more appropriate as they are designed to remove larger portions of prostate tissue to alleviate obstruction. However, TUIP remains a less invasive and effective choice for smaller prostates, making it the recommended procedure in such cases.

Watchful waiting is an option for managing mild symptoms or when intervention is not immediately necessary, but it is not a surgical procedure. Therefore, when surgical intervention is indicated for smaller prostates, TUIP is preferred.
