Was told I have kidney stone in kidney. What size can pass through penis?

Was told I have kidney stone in kidney. What size can pass through penis?

Moderate: Basically anything that can get down the ureter into the bladder, can easily pass through the penis tubes (urethra). If your stones are in the kidney, they may be in the pelvis of the kidney and can be quite large. A piece of this could break off and cause the famous, painfull kidney stone passage through the ureters. You should be evaluated by a urologist for kidney stones before this happens. ...Read more

My fiancee got a kidney stone of 6mm in size according to the ultrasound, is it possible to pass it without surgery?

Ureteral stone: The size of the stone does not correlate well to the intensity of the pain. The nearly unbearable pain of "ureteral colic" is from spasm of the muscular ureter. Although likely to pass on its own within a few days, a 3mm stone sometimes will get stuck and fail to progress. A 6mm stone, less likely usually after 5 days, i recommend having the stone extracted with a ureteroscope as an outpatient. ...Read more
