Prenatal Hydronephrosis Treatment
Sometimes, hydronephrosis goes away without treatment. Often, mild cases do not adversely affect kidney function and require only monitoring.
Treatment is required only when kidney function is impaired or the kidney becomes greatly enlarged. The underlying cause of hydronephrosis determines the course of treatment.
Long-term follow-up is recommended for hydronephrosis, regardless of treatment type. Periodic ultrasounds to monitor the kidneys are recommended once kidney function and growth are stable.
Most cases of vesicoureteral reflux are treated with daily antibiotic therapy. Prenatal hydronephrosis is often treated with antibiotics to prevent kidney infections.
In cases where surgery is recommended, the operation is highly successful and carries relatively little risk.
For severe UPJ obstruction, surgery is usually required. The operation to correct UPJ obstruction is called a pyeloplasty. Usually this surgery is performed through an incision in the side.
With recent advances in minimally invasive surgical techniques, pediatric urologists can correct UPJ obstruction without the need for open surgery. The new technique provides significant benefits in reduced postoperative pain, faster recovery, and minimal sca rs.
In one such procedure, called laparascopic pyeloplasty, a laparascope (a slim tube with a tiny video camera mounted on the end) is inserted into a small incision in the navel. While watching the procedure on a TV monitor, the surgeon inserts instruments throu gh other small incisions to repair the obstruction.
The blocked part of the ureter is removed and the healthy ureter reconnected to the kidney. A temporary tube called a stent may be placed inside the ureter to drain the kidney until surgery heals.
Currently, this operation is being used in older children and adults, although eventually it will be applicable to toddlers or even infants. The hospital stay for either open or laparoscopic pyeloplasty is usually only one to three days.
The success rate is generally 95 percent for all open operations, and appears to be similar for the laparoscopic operation.
