What is a reoperation rate?

A reoperation rate is the percentage of patients who had a particular urologic surgery at Children’s Hospital Colorado and needed an unanticipated second surgery with a minimum of a one-year follow-up. (Note: 95% of patients who need a second surgery will have one within a year).

Why do we measure urologic surgery outcomes and reoperation rates?

Our urology team is dedicated to improving patient outcomes. We measure the rate of reoperation to help us evaluate how we treat certain pediatric illnesses and to continually improve the quality of care for kids. By publishing and analyzing reoperation rates, we hope to identify situations where reoperation commonly happens and find solutions to reduce it.

Currently, Children’s Colorado is one of the few pediatric hospitals in the country that publishes the outcomes of these surgeries to help parents make educated decisions about their child’s healthcare.

How have we improved our reoperation rates?

We are continually striving to improve our outcomes by reviewing our techniques and following national and international best practices.

Children’s Colorado reoperation rate for hypospadias surgery

What is hypospadias?

Hypospadias is a condition in which the urethral tube opening is not at the tip of the penis. Instead, it is located underneath it. The surgical repair of hypospadias creates an opening in the correct place.

In 2019, only six of our 80 patients who had a hypospadias repair needed a reoperation. Only 7.5% of patients who had surgical repair of hypospadias at Children’s Colorado needed another operation. This is comparable with recently published data by Warren T. Snodgrass, which states an overall complication rate of 11.5%.

About this data

What is the source of this data?

The data is collected by the Department of Pediatric Urology at Children’s Colorado.

How do we compare ourselves to other hospitals?

To gather this data, Children’s Colorado used benchmarks in the book “Pediatric Urology Surgical Complications and Management,” 2015, published by Wiley Blackwell (specifically, we referred to chapters by Warren T. Snodgrass, Kim Hutton and Henrik Steinbrecher). This book compares the complication rates of urologic procedures from hospitals across the U.S. and Europe.

How often will this data be updated?

The Department of Pediatric Urology tracks each patient’s success for an entire year and will continue to update this information.
