My son he is 7 weeks old.. At 26th week USG renal pelviectasis was ruled out..  Within 2 weeks I went for second opinion and doctor said kidneys are normal..  Now He often cries and couldn't tolerate penis erection.. Initially I thought it's because he gonna urinate tats why he is crying but now am noticing tat he doesn't have the urge to urinate but he cries when his penis gets erected..i am not sure whether tat erection and pain is connected with his urination.. Or it's due to renal pelviectasis.. During erection at night he cries badly and curves his body until tat erection stops. He s getting disturbed from sleep because of this erection.. This erection is lasting for few seconds then he s okay.. Wat would be the problem sir/ madam... Reply me please..
