Causes

Life-threatening Causes

  • Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. There are no life-threatening causes of hydronephrosis, however, complications resulting from untreated hydronephrosis are common.

Common Causes

  • Hydronephrosis is most commonly caused by urinary tract obstruction anywhere from kidneys to the urethral opening. It is also caused by non-obstructive conditions.
  • The following table summarizes the common causes of hydronephrosis.
Kidneys[1][2][3][4] Renal calculi

Carcinoma involving kidneys

Sloughed renal papilla

Ureter[5][6][7][8][9][10][11][12][13][14][15][16] Ureteral calculi

Retroperitoneal fibrosis

Blood clots retention

Transitional cell carcinoma of the ureter

Sloughed papilla and renal papillary necrosis obstructing the ureter

Infections

Ureteral strictures by traumaiatrogenic injuryradiation

Ureteropelvic junction obstruction

Extrinsic tumors and masses causing compression and hydronephrosis (eg, inguinal hernia, retroperitoneal lymph nodes, retroperitoneal tumors, prostate cancercervical and endometrial tumors and abdominal malignancies)

Bladder[17][18][19][20][21][22][23][24][25] Bladder cancer (eg, transitional cell carcinoma of the bladder)

Bladder calculi

Neurogenic bladder

Vesicoureteral reflux

Inflammation of the bladder (eg, radiation, endometriosis)

Bladder hypertrophy

Bladder-neck obstruction

Urethra[26][27][28] Urethral strictures (eg, Bacterial urethritis, Indwelling urinary catheter, prostate surgeries, cystoscopy)

Prostate enlargement (Benign prostatic hyperplasia and hypertrophy)

Urethral Urethral valves (Posterior urethral valves, and anterior urethral valves)

Less Common Causes

Less common causes of disease name include:

  • Fungal ball[29]
  • Ketamine abuse [30]
  • Physiologic hydronephrosis may be seen in pregnancy.[31]
  • Pelvic lipomatosis[32]
