Post-Hysterectomy Transient Hydronephrosis: A Prospective Study

Area of Science:

• Urology
• Gynecology
• Radiology

Background:

• Post-hysterectomy complications require careful monitoring.
• Transient hydronephrosis is a potential, though often asymptomatic, complication.

Purpose of the Study:

• To investigate the incidence and significance of transient asymptomatic hydronephrosis after total hysterectomy.
• To identify factors influencing the occurrence and severity of post-hysterectomy hydronephrosis.

Main Methods:

• Prospective study of 368 women undergoing total abdominal or vaginal hysterectomy.
• Renal ultrasonography performed pre-operatively and at 3, 7, and 28 days post-surgery.
• Intravenous urography used for persistent, progressive, or symptomatic hydronephrosis.

Main Results:

• No intraoperative ureteral injuries were identified.
• Hydronephrosis observed in 9.5% at day 3, 5.7% at day 7, and 0.27% at day 28.
• Right kidney more frequently affected; incidence correlated with surgical indication, duration, route, and patient age.

Conclusions:

• Transient hydronephrosis is a possible complication of total hysterectomy, occurring in 9.5% of patients within 3 days.
• The condition generally resolves spontaneously within one month, often without intervention.
• Emphasizes the need for vigilance and imaging surveillance following hysterectomy, even in uncomplicated cases.
