Had utis for 10 months. told i have hydronephrosis in left kidney and swelling in right. is it safe to wait 4 weeks for urologist appointment?

See a urologist: Suggest that you call the urologist's office and ask if you can speak with them or their nurse and explain the issues and get their advice on whether waiting is ok. Might be better if you could get your pcp to do this since the response might be more forthcoming. Good luck and best wishes.

Sooner: Probably need to see a urologist sooner than later. It depends on the xray findings and the severity of the hydronephrosis.

sooner is better: Of course the sooner these things are evaluated and corrected the better. It is clearly abnormal on several levels, the uti, the obstruction and the renal edema.

Here are some...: You need to ask three Qs: First, your UTIs are in bladder or indeed in kidneys; second, do you have symptoms related with kidney swelling and hydronephrosis; third, have you had Hx of recurrent UTI & diabetes? If just having bladder infections and being asymptomatic, waiting for 4 wks would not make a difference in outcome. So, seek timely evaluation so to decide the urgency of care.
