Patient's question:
A while ago, I happened to notice that my penis was a bit different from others. Others could expose their glans, but mine couldn't. My foreskin couldn't be retracted at all, and I was very worried it might be phimosis.What kind of help do I need: What are the main symptoms of phimosis?
Doctor's answer:
Phimosis is mostly congenital. A small portion is caused by repeated infections due to excessive prepuce, leading to adhesions that prevent it from being retracted. Compared to prepuce redundancy, phimosis poses greater harm to the human body. In some severe cases of phimosis, the preputial orifice is narrow like a needlehole, and the prepuce swells like a ball during urination, causing difficulty in urination. Due to the narrowed urethral orifice, the bladder sphincter contracts during urination. Before or simultaneously with the removal of urethral resistance, the intravesical pressure is also lower than the pressure that the bladder's mucous membrane can withstand. Urine refluxes along the ureters, causing dilation of the ureters and renal pelvis, leading to upper urinary tract bacterial infections, scar formation, and ultimately secondary reflux nephropathy or even kidney function damage.
