ObjectiveTo characterize academic urology Twitter presence and interaction by subspecialty designation. MethodsUsing Twitter application programming interface of available data, 94000 specific tweets were extracted for the analysis through the Twitter Developer Program. Academic urologists were defined based on American Urological Association (AUA) residency program registration of 143 residency programs, with a total of 2377 faculty. Two of 3-factor verification (name, location, specialty) of faculty Twitter account was used. Additional faculty information including sex, program location, and subspecialty were manually recorded. All elements of microblogging were captured through Anaconda Navigator. Analyzed tweets were further evaluated using natural language processing for sentiment association, mentions, and quote tweeted and retweeted. Network analysis based on interactions of academic urologist within specialty for given topic were analyzed using D3 in JavaScript. Analysis was performed in Python and R. ResultsWe identified 143 residency programs with a total of 2377 faculty (1975 men and 402 women). Among all faculty, 945 (39.7%) had registered Twitter accounts, with the majority being men (759 [80.40%] versus 185 [19.60%]). Although there were more male academic urologists across programs, women within academic urology were more likely to have a registered Twitter account overall (46% versus 38.5%) compared with men. When assessing registered accounts by sex, there was a peak for male faculty in 2014 (10.05% of all accounts registered) and peak for female faculty in 2015 (2.65%). There was no notable change in faculty account registration during COVID-19 (2019–2020). In 2022, oncology represented the highest total number of registered Twitter users (225), with the highest number of total tweets (24622), followers (138541), and tweets per user per day (0.32). However, andrology (50%) and reconstruction (51.3%) were 2 of the highest proportionally represented subspecialties within academic urology. Within the context of conversation surrounding a specified topic (#aua21), female pelvic medicine and reconstructive surgery (FPMRS) and endourology demonstrated the total highest number of intersubspecialty conversations. ConclusionsThere is a steady increase in Twitter representation among academic urologists, largely unaffected by COVID-19. While urologic oncology represents the largest group, andrology and reconstructive urology represent the highest proportion of their respective subspecialties. Interaction analysis highlights the variant interaction among subspecialties based on topic, with strong direct ties between endourology, FPMRS, and oncology.

We present a case of refractory cystitis after BK-virus associated hemorrhagic cystitis following bone marrow transplantation requiring cystectomy in a 17-year-old female with genetically confirmed dyskeratosis congenita, a telomere disorder characterized by early bone marrow failure. She presented with a contracted, small bladder with intense urinary symptoms non-responsive to conservative therapy and requiring opioids for pain control. Cystectomy is a rare, final surgical treatment for benign bladder conditions, especially among younger patients, and she experienced successful resolution of symptoms and cessation of chronic opioids post-intervention.

We report the case of a 4 year old female with severe traumatic brain injury who developed bilateral obstructing ureteral stones after hypertonic saline treatment. She developed calcium phosphate stones after two weeks of hypertonic saline therapy, and was successfully treated with ureteral stents and ureteroscopy. She has remained stone-free since that time. We postulate that an incomplete type 1 renal tubular acidosis made her intolerant to the acid and sodium load of the saline, and discuss other lithogenic factors of her presentation.

PurposePercutaneous surgery is an established approach to a spectrum of renal pathology, and hemorrhage is the most concerning complication of this technique. We determined the frequency of postoperative hemorrhage requiring selective angioembolization (SAE), the efficacy of this approach, and characterized the angiographic findings.MethodsWe reviewed our database of 4695 patients who underwent percutaneous renal surgery and identified patients requiring SAE for postoperative hemorrhage. Angiographic findings were recorded and efficacy of SAE documented.ResultsPatients undergoing percutaneous stone extraction (PSE; 3685), percutaneous antegrade endopyelotomy (PAE; 850), and upper-tract transitional cell carcinoma (UTTCC) resection (160) were reviewed. We identified 57 patients requiring SAE (1.2) who underwent 44 PSEs (77.2), 7 PAEs (12.3), and 6 UTTCC resections (10.5). This represented 1.2, 0.8, and 3.2 of all PSE, PAE, and UTTCC resections, respectively. Angiography revealed treatable lesions in 94.7 of patients. Overall, 64 angiographic findings were encountered including 30 pseudoaneurysms (53 of patients, 47 of findings), 14 arteriovenous fistulas (AVFs) (25 of patients, 22 of findings), and 14 instances of contrast extravasation (25 of patients, 22 of findings). Two arterial dissections and one instance each of a hypervascular area, a vascular “cut-off” sign, and a fistula between an artery and the percutaneous tract were identified. One bleeding vessel identified at the base of a UTTCC resection was not amenable to embolization. Ten patients (17.5) had ≥1 angiographic finding. Three patients (5.3) had no angiographic findings to account for hemorrhage. No angioembolization-related complications occurred. Complete resolution of bleeding was observed in 54 patients (95).ConclusionsMajor hemorrhage requiring intervention after percutaneous renal surgery is uncommon. The most common angiographic finding is arterial pseudoaneurysm, followed by arteriovenous fistula, and contrast extravasation. In 95 of cases angiography reveals a demonstrable and treatable etiology. This strongly supports the first-line use of angiography for intractable bleeding in this setting. [ABSTRACT FROM AUTHOR]
