Congenital Megacalcycosis
by Sharon__0__0, Dec 15, 1998 12:00AM
My 15 year old son was diagnosed with hydronephrosis following
a bone scan for a back injury from football. Further ultrasound
testing revealed the nephrosis to be mild to moderate, due to
possible UPJ obstruction.An IVP was performed to rule out the UPJ
obstruction,and no obstruction was found. However, the doctor
now says this may be Congenital Megacalycosis and that he should
be monitored for any changes. I should mention that he has never
had any history of UTI's or any other urologic problems. My
question is this: Is there any treatment for this condition, if
so what is it? If left as is, can this lead to kidney damage? I
have been searching the internet for information regarding this
condition but have not had luck finding anything!
Thank you for any information you can give me.

Dear Sharon
Thanks for your questions.
Irreversible renal damage from a ureteropelvic junction obstruction can occur if there is a “significant” and “chronic” obstruction. Since the IVP showed no obstruction there is no reason to expect renal failure in the future. A renal scan can be performed if the hydronephrosis gets worse. This test can document the differential function each kidney contributes to the total renal function. Even if he lost entire function of this kidney, he will not need dialysis, assuming the other kidney is normal. He has had this for 15 years , has never bothered him and probably never will.
If his UPJO becomes symptomatic (,i.e. flank pain , UTI’s or significant hydronephrosis with obstruction), surgery to correct this narrowing is the treatment of choice.
More individualized care is available at the Henry Ford Hospital and its urban campuses by calling (1 800 653 6568). We can also arrange local accommodations through this number if this is your need. Please bring any physicians’ notes and lab test results that you may be able to obtain. These will help us greatly.
