Patient: Bilateral hydrocele was detected during physical examination, but there is no disease. 3 years have passed without treatment, it will not cause kidney damage, right? Many Chinese people always use “can I eat” and “am I in pain” as the criteria for going to the hospital. Early and middle stage kidney stones and hydronephrosis can be asymptomatic, but when symptoms appear in the later stage, it often causes irreversible kidney function damage. You have clear kidney stones and hydronephrosis, I suggest that you first take blood to check the kidney function to see if the creatinine and other values are high, to determine the degree of kidney function damage; then further intravenous pyelogram (if the kidney function is not good, then retrograde pyelogram, renal nuclear scan), to clarify the next step of treatment. The options are: 1) Chinese and western medicine combination to promote stone removal; 2) ESWL extracorporeal shock wave lithotripsy; 3) MPCNL percutaneous nephrostomy lithotripsy; 3) open surgery nephrectomy for stone removal if necessary.
