To evaluate the urethroplasty learning curve. Published success rates of urethral reconstruction for urethral stricture disease are high even though these procedures can be technically demanding. It is likely that success rates improve with time although a learning curve for urethral reconstruction has never been established.
We retrospectively reviewed anterior urethroplasties from a prospectively maintained multi-institutional database. Success was analyzed at the 18-month mark in all patients and defined as freedom from secondary operation for stricture recurrence. A multivariate logistic regression was performed for outcomes versus time since fellowship and case number.
A total of 613 consecutive cases from six surgeons were analyzed, with a functional success rate of 87.3%. The success for bulbar urethroplasties was higher than for penile urethroplasties (88.2% vs 78.3%, p = 0.0116). The success of anastomotic repairs was higher than for substitution repairs (95.0% vs 82.4%, p = 0.0001). There was a statistically significant trend towards improved outcomes with increasing number of cases (p = 0.0422), which was most pronounced with bulbar repairs. There was no statistical improvement in penile repairs over time. The case number to reach proficiency (> 90% success), was approximately 100 cases for all types of reconstruction were considered and 70 cases for bulbar urethroplasties. There were statistical differences in success rates among the participating surgeons (p = 0.0014). Complications decreased with time (p = 0.0053).
This study shows success rates of anterior urethral reconstruction improve significantly with surgeon experience. Proficiency occurs after approximately 100 cases.
This research output has an Altmetric Attention Score of 9. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 February 2017.
All research outputs
#5,342,898
of 32,304,778 outputs
Outputs from Urology
#1,569
of 9,659 outputs
Outputs of similar age
#67,948
of 429,402 outputs
Outputs of similar age from Urology
#21
of 154 outputs
Altmetric has tracked 32,304,778 research outputs across all sources so far. Compared to these this one has done well and is in the 83rd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 9,659 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.6. This one has done well, scoring higher than 83% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 429,402 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 84% of its contemporaries.
We're also able to compare this research output to 154 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 86% of its contemporaries.
