Can you have sex with hydronephrosis?

Before the complete resolution of hydronephrosis, it is recommended that patients avoid sexual intercourse. This is because hydronephrosis indicates the presence of obstructive factors in the urinary system, causing urine to not be excreted smoothly. Urine accumulates within the urinary system, causing dilation of the renal pelvis, calyces, and ureter. If urine cannot be excreted, bacteria can easily ascend from the urethral opening into the urinary system, causing an inflammatory response. If patients engage in sexual intercourse during this time, bacteria at the urethral opening can easily be pressed into the bladder, ascending and potentially causing pyelonephritis or cystitis. Therefore, it is best for such patients to avoid sexual intercourse until the hydronephrosis has been thoroughly addressed.

What are the symptoms of hydronephrosis?

Patients with hydronephrosis may not exhibit any symptoms. Whether symptoms are present depends on factors such as the extent of renal damage caused by hydronephrosis, the severity of the hydronephrosis, and the duration of hydronephrosis. Some patients might only notice the issue due to a lump in the abdomen or a swelling sensation in the lower back, prompting them to undergo ultrasound imaging that reveals hydronephrosis. Hydronephrosis can cause renal colic, and patients may also experience nausea, vomiting, and reduced urine output. When hydronephrosis is complicated by infection, symptoms like chills, shivering, fever, and headache can occur. Some patients may first present clinically with a urinary tract infection, showing symptoms like fever, frequent urination, urgent urination, and painful urination. In rare cases, hydronephrosis can rupture and lead to bleeding.
