Welcome To Health Care Magic,
having more than 2 kidney is known as -SUPERNUMERARY KIDNEY.
It happens due to splitting of nephrogenic blastema or from seperate metanephric blastemas into which partially or completely reduplicated ureteral stalks enter to form seperated capsulated kidneys.
This condition is very rare and does not require any treatment till unsymptomatic.
Take care

Thanks for writing to us.
You are having a rare condition called supernumerary kidneys. These are asymptomatic and are usually diagnosed on a routine ultrasound scan. There is nothing to worry. This is just a variation from normal. Renal functions are preserved normally.
I hope this information has been both informative and helpful for you.

hi welcome to HCM.A supernumerary kidney is an additional kidney to the number usually present in an organism. This often develops as the result of splitting of the nephrogenic blastema, or from separate metanephric blastemas into which partially or completely reduplicated ureteral stalks enter to form separate capsulated kidneys; in some cases the separation of the reduplicated organ is incomplete (fused supernumerary kidney). supernumerary ureter in most fully documented cases of double ureters. Pathologic conditions of the upper urinary tract occurred in more than 50 per cent of the patients with a bifid system, who were prone to have hydronephrosis and calculous disease, and with a double system, who were prone to have complications resulting from supernumerary ureteral ectopia.
