| Abstract |
Complex ureteric strictures present a significant challenge to the endourologist and uro-radiologist. Multiple separate interventions to try to cross the stricture are often attempted. We describe our experience managing a heterogenous patient group using the 'rendezvous' procedure. 16 patients and 18 ureters (one bilateral procedure, and two separate procedures in one patient) underwent rendezvous procedures. Seven patients had coexisting ureteric calculi treated. Each case was followed up for between 3 months and 5 years. In 16/18 ureters there was technical success at time of surgery; successfully crossing the stricture, allowing ureteroscopic access to the ureter, dilating and/or stenting the ureter. 2/18 were unsuccessful; one secondary to advanced malignancy resulting in a uretero-vaginal fistula and the second a failure to remove a retained, displaced ureteric stent. Of the 18 ureteric procedures; 7/18 were stent free at 3 months, improving to 8/18 stent free at 6 months. 4/18 remained nephrostomy dependent (failure of drainage despite stent or failure to stent) at 3 months, increasing to 6/18 being nephrostomy dependent at 6 months. 1/16 remained dialysis dependent with a nephrostomy tube. For those procedures involving ureteric calculi, 6/7 were stone free and 1/5 had a persistent stone fragment requiring further intervention. A combined approach may decrease the number of separate interventions required, with the aim of removing the need for a long-term nephrostomy, as well as providing opportunity to treat ureteric calculi in the context of stricture disease. Our experience has been that where the rendezvous has been required to treat strictures caused by malignant extrinsic compression, stenting has not been successful; this information is key to informed consent in a group of patients who may have a limited life expectancy. |

Attention Score in Context
This research output has an Altmetric Attention Score of 5. 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 07 July 2018.
All research outputs
#6,503,438
of 23,094,276 outputs
Outputs from Urolithiasis
#111
of 332 outputs
Outputs of similar age
#113,731
of 329,246 outputs
Outputs of similar age from Urolithiasis
#4
of 6 outputs
Altmetric has tracked 23,094,276 research outputs across all sources so far. This one has received more attention than most of these and is in the 71st percentile.
So far Altmetric has tracked 332 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.1. This one has gotten more attention than average, scoring higher than 66% 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 329,246 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 65% of its contemporaries.
We're also able to compare this research output to 6 others from the same source and published within six weeks on either side of this one. This one has scored higher than 2 of them.
