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 is hydronephrosis?

The so-called hydronephrosis is a morphological description, referring to an obstruction in the urinary system caused by various reasons. After the kidneys produce urine, it cannot be normally delivered to the bladder. This leads to fluid accumulation in the renal pelvis and calyces, which can be detected through imaging as hydronephrosis. The causes of hydronephrosis are numerous. The most common cause is acquired obstruction, primarily due to urinary system stones, scarring from injuries, or tumors in the urinary system compressing the ureter, which often results in urinary tract obstruction. In addition, some congenital causes can also lead to urinary tract obstruction. Examples include segmental dysfunction of the ureter, intrinsic stenosis of the ureter, and twisting of the ureter. However, these congenital obstruction causes are relatively rare.

What department to see for hydronephrosis?

Patients with hydronephrosis should visit the urology department of a formal hospital, because the conditions causing hydronephrosis are often surgical in nature. The most common cause is urological stones, which block the ureter or the bladder opening, causing urine to accumulate within the urinary system and leading to hydronephrosis. Additionally, patients with benign prostatic hyperplasia may also experience this condition. Tumors in the urinary system may compress the ureter and cause hydronephrosis. Some patients have congenital deformities of the ureter, where changes in the anatomical structure can lead to hydronephrosis. In summary, these conditions often require surgical treatment, thus necessitating consultation at a formal hospital's urology department.

Is hydronephrosis serious?

Whether the condition of hydronephrosis is serious depends on various factors such as the duration of hydronephrosis, the cause, the extent of fluid accumulation, and more. For example, some patients may have mild hydronephrosis in only one kidney and it may have developed recently; generally, this condition is not very serious. Some patients might have urinary obstructions caused by urinary system stones, and the issue could be resolved using extracorporeal shock wave lithotripsy or surgical stone removal, making the condition not serious. However, in some cases, the cause could be bladder cancer or a tumor near the urinary system compressing the ureter, and if the tumor is difficult to remove, the hydronephrosis might be hard to manage. Long-term fluid accumulation might lead to kidney failure, and these scenarios are considered quite serious.

What tea to drink for hydronephrosis

Before hydronephrosis is adequately treated and before the obstruction in the urinary system is resolved, in areas such as the renal pelvis and calyces where there is fluid accumulation, it is advised that patients should not drink tea and should try to reduce their fluid intake. This is because the fluids cannot be excreted through the kidneys, and drinking large amounts of water at this time could worsen the obstruction and may also lead to edema. Therefore, patients are advised not to drink tea until the hydronephrosis is resolved. Once the causes of urinary tract obstruction, such as urinary system stones or tumors, have been removed, patients can increase their water intake, but it is still recommended not to drink tea because tea contains considerable amounts of oxalate, which can lead to the recurrence of kidney stones.

Should people with hydronephrosis avoid certain foods?

Although there are many causes leading to hydronephrosis in patients, most hydronephrosis is related to stones, meaning that hydronephrosis occurs in patients due to ureteral kidney stones. Therefore, dietary restrictions are necessary for patients with hydronephrosis in daily life. If the hydronephrosis is caused by calcium oxalate stones, patients should avoid consuming foods that are high in calcium and oxalates, such as nuts, legumes, spinach, and beets. If the hydronephrosis is due to the formation of uric acid stones, patients should also avoid consuming excessive amounts of animal organs, such as pork liver and kidneys, avoid seafood, and try not to drink beer, as these contain a high amount of purines, which can easily lead to stone formation. Additionally, if patients with hydronephrosis also have renal insufficiency, they should follow a low-salt diet and avoid consuming particularly salty foods, including various pickles, etc.
