Implantation of a penile prosthesis in a patient with significant corporal fibrosis can pose a significant challenge to the surgeon, necessitating the knowledge of specific techniques used to dilate and close aggressively scarred corpora. The objective of our instructional video is to discuss 2 techniques used to approach corporal fibrosis: proper and safe use of cavernotomes for dilation and use of narrower prostheses.
In this video, we present a 53-year-old man with a history of priapism 3 years ago that lasted 4 days in the setting of trazodone use. He was managed with corporal irrigation and subsequently developed severe erectile dysfunction. Notably, the patient had a history of sickle cell anemia, and on physical examination was noted to have densely fibrotic corpora. After extensive counseling regarding options, he chose a penile implant. The surgical was planned using the "no touch technique." After the corporotomies were made, we began dilating the corpora. Hegar dilators and Dilamezinsert were attempted at first but met significant resistance. We switched to cutting cavernotomes and were able to dilate up to 11-Fr distally and up to 13-Fr proximally. The proper use of cavernotomes is highlighted in our video, with care being taken to aim the cutting edge of the cavernotome laterally away from the urethra. We also used the narrowest inflatable prosthesis available to us (Coloplast Titan narrow-base) and describe the narrower devices available in inflatable and malleable forms as an option for less-than-ideally dilated corpora. The pump and reservoir placement was completed uneventfully.
The patient was admitted overnight for observation and check of a complete blood count given his history of sickle cell anemia. He was able to be discharged after 23 hours of observation. The patient presented to the clinic 4 weeks later for pump activation. He was able to achieve good rigidity and had a penile length adequate for penetration after maximal activation.
This video discusses the approach to penile prosthesis placement in patients with significant corporal fibrosis. It highlights the proper use of cutting cavernotomes and the availability of narrow-diameter prostheses, both malleable and inflatable.
This research output has an Altmetric Attention Score of 3. 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 18 August 2017.
All research outputs
#9,754,446
of 28,494,563 outputs
Outputs from Urology
#3,655
of 9,041 outputs
Outputs of similar age
#130,229
of 331,435 outputs
Outputs of similar age from Urology
#73
of 181 outputs
Altmetric has tracked 28,494,563 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 9,041 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.6. This one is in the 34th percentile – i.e., 34% of its peers scored the same or lower than it.
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 331,435 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 50% of its contemporaries.
We're also able to compare this research output to 181 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 59% of its contemporaries.
