Patient's question:
Having a circumcision surgery, the ring naturally falls off after 20 days. After the ring fell off, I also checked my child's penis and it looked smooth. However, in recent days, I noticed brown spots on my child's underwear, which don't wash off. I don't know where these brown spots are coming from and whether they are related. Thank you!Doctor's answer:
The majority of phimosis is congenital. Some cases result from repeated infections due to excessive foreskin, leading to adhesions that prevent retraction. Phimosis poses greater harm to the human body compared to excessive foreskin. In severe cases of phimosis, the foreskin opening is narrow like a needlehole, causing the foreskin to bulge like a ball during urination, leading to difficulty urinating. Due to the narrowed urethral opening in phimosis, the bladder sphincter contracts during urination. Before or simultaneously with overcoming the urethral resistance, the bladder pressure exceeds the pressure that the bladder's Mauers' sheath can withstand. Urine refluxes into the ureters, causing dilation of the ureters and renal pelvis, leading to upper urinary tract bacterial infections, scar formation, and secondary reflux nephropathy, even kidney damage.Long-term chronic irritation from urine and smegma due to excessive foreskin or phimosis can cause edema, congestion, erosion, and repeated cross-infections of the foreskin and glans mucosa, even leading to phimosis entrapment, resulting in severe consequences such as necrosis of the foreskin and glans. Additionally, it can transmit pathogens to the female body during sexual intercourse. Excessive foreskin and phimosis have long plagued human health and must be highly valued by male citizens.
