The Lab Tests were done in connection with his present problem of urination esp. at night time.   Whether without surgery this cyst can be eradicated or not ? Whether the urination problem is correlated with this cyst ? Kindly advise in this regard.
[|AI|]  Hello, I have studied your case. Cyst of 15 mm size is quite large and can not be eradicated without surgery. Residual urine volume is large indicating bladder out let obstruction. For finding functional status of kidney you may need to do further investigation like MVP, genogram. Problem may not be related to cyst. Hope this answers your query.
