Background: In this report, we describe a modification of transcorporal artificial urinary sphincter place ment known as Gullwing modification.

Description of technique: Using a penoscrotal approach, bilateral corpora cavernosa flaps are harvested and sutured in the midline covering the lateral and ventral surfaces of the urethra. Transcorporal cuff placement provides dorsal reinforcement, thus having extra tissue buttressing all the circumference in cases of a fragile urethra due to previous urethral cuff erosion, urethroplasty, or pelvic radiotherapy.

Patient and methods: After previous urethral cuff erosion, radiotherapy, and urethral reconstruction, our patient complained of severe stress urinary incontinence. Due to the high risk of urethral complications, we proceed to a transcorporal artificial sphincter placement with urethral reinforcement through a bilateral cavernosal flap.

Results: The surgery was successfully completed, and after 6 weeks, sphincter was activated with satisfac tory results. Two years after surgery, his continence status is stable without complications.

Conclusion: Urethral complications associated with artificial urinary sphincter surgery remain a challenge for the reconstructive surgeon. Reinforcement of the ventral aspect of the urethra through corpora cavernosal flaps may reduce the likelihood of urethral erosion in high-risk cases.

Objective: Our study investigated the oldest known Turkish bahname, translated by Musa b. Mes'ud, in comparison with the current literature.

Material and methods: First, the original manuscript of the translation was transcribed in Latin. The final version of the text was analyzed in the results. In discussion, findings were examined and interpreted within the framework of current knowledge of sexology, urology, and andrology.

Results: Although the work mostly mentions supportive and therapeutic practices in sexual health, it also provides advice on sexuality and sexual life, discussing several topics regarding sexual intercourse types, explaining which ones are good or harmful, and their timing or frequency. The author recommends many foods and compounds or specific drugs and ointments to enhance sexual stamina and avoid erectile dysfunc tion. In addition, he also tries to find solutions to some other sexual health problems related to men and women. These issues are generally evaluated in the context of health; a religious perspective is also provided when needed.

Conclusion: Interestingly, the author's recommendations on sexual health and herbal or animal drugs are consistent with the current literature. Nevertheless, some information and suggestions in works are entirely irrational and unscientific. Consequently, this study is an original investigation of the first translated bahname into Turkish. There is no other study examining the bahnames with this method. Thus, we believe that our work will be a significant contribution to the research literature.

Background: Gender-affirming surgery leads to high satisfaction for patients; however, patients often require revision surgery. Revision labiaplasty is one of the most common surgeries following vaginoplasty. The labia minora commonly become incorporated into the labia majora and lose definition even after revision leading to patient dissatisfaction.

Description of technique: We propose a technique of incorporating cadaveric costal cartilage allograft into the revised labia minora to increase the definition.

Patient and methods: The procedure was demonstrated in a 38-year-old MTF patient who had previously undergone inversion vaginoplasty. The cartilage allograft was incorporated within the labia minora flaps dur ing labiaplasty.

Results: The patient had lasting definition of her labia minora post-operatively at 6 weeks without adverse effects.

Conclusion: We believe that this technique may be effective and safe in patients requesting more defined labia minora after vaginoplasty.

Intestinal microbiota is a topical subject of modern research. The maintenance of a healthy intestinal micro biota is an important component of homeostasis, and violations of its composition and functions, called dysbiosis, are associated with a number of diseases, including urinary tract infections. Antimicrobial therapy leads to significant changes in the intestinal microbiota and causes the possibility of urinary tract infection recurrence. In this regard, it is important to study methods of microbiota correction in order to restore its structural and functional integrity.

Objective: This study was designed to describe our hybrid approach to intracorporeal urinary diversion and evaluate surgical experience during initial induction.

Material and methods: Clinical data from 38 patients with bladder cancer undergoing robot-assisted radical cystectomy with ileal conduit hybrid approach to intracorporeal urinary diversion at our institution between May 2020 and January 2022 were reviewed. The hybrid approach to intracorporeal urinary diversion pro cedure involved the following: radical cystectomy, removing a specimen through a 4- to 6-cm skin incision, harvesting an ileal conduit, redocking the robot, and uretero-uretero anastomosis. The relationship between surgical experience and operative time and a Clavien-Dindo classification of grade >3 was evaluated.

Results: Of the 38 patients, 30 (79%) were male, and the median age was 75 years (interquartile range, 71-80 years). The total operative time was 384 minutes (interquartile range, 348-409 minutes). The estimated blood loss was 244 mL (interquartile range, 124-445 mL). No bowel injuries or conversions to laparoscopy or laparotomy were encountered. High-grade postoperative complications (Clavien-Dindo classification grade > 3) occurred in 7 cases (19%). The overall 90-day readmission rate following discharge after surgery was 5%. The relationship between surgical experience and operative time was nonlinear. A plateau was not reached in all 38 patients.

Conclusion: Our hybrid approach to intracorporeal urinary diversion technique can be accomplished safely with acceptable operative times, even with little surgical experience. This procedure might be a safe treat ment option that is relatively easy to perform, particularly in an institution that has not yet introduced intra corporeal urinary diversion. Future randomized trials with larger samples and longer follow-up periods are required to confirm our findings.

Objective: Diagnostic ureterorenoscopy is used to identify upper tract urothelial cancer before radical nephro ureterectomy, especially for uncertain lesions in imaging modalities or urine cytology. However, diagnostic ureterorenoscopy can potentially cause intravesical tumor spillage and can increase intravesical recurrence rates. We aimed to investigate the impact of diagnostic ureterorenoscopy before radical nephroureterectomy, with and without biopsy, on intravesical recurrence rates of patients with upper tract urothelial cancer.

Material and methods: Patients with localized upper tract urothelial cancer from 8 different tertiary referral centers, who underwent radical nephroureterectomy between 2001 and 2020, were included. Three groups were made: no URS (group 1); diagnostic ureterorenoscopy without biopsy (group 2); and diagnostic ure terorenoscopy with biopsy (group 3). Intravesical recurrence rates and survival outcomes were compared. Univariate and multivariate Cox regression analyses were performed to determine the factors that were asso ciated with intravesical recurrence-free survival.

Results: Twenty-two (20.8%), 10 (24.4%), and 23 (39%) patients experienced intravesical recurrence in groups 1, 2, and 3, respectively (P=.037) among 206 patients. The 2-year intravesical recurrence-free sur vival rate was 83.1%, 82.4%, and 69.2%, for groups 1, 2, and 3, respectively (P=.004). Cancer-specific survival and overall survival were comparable (P=.560 and P=.803, respectively). Diagnostic ureterore noscopy+biopsy (hazard ratio: 6.88, 95% CI: 2.41-19.65, P < .001) was the only independent predictor of intravesical recurrence in patients with upper tract urothelial cancer located in the kidney, according to tumor location.

Conclusion: Diagnostic ureterorenoscopy+biopsy before radical nephroureterectomy significantly increased the rates of intravesical recurrence in tumors located in kidney. This result suggests tumor spillage with this type of biopsy, so further studies with different biopsy options or without biopsy can be designed.

Objective: Urogenital tuberculosis and disseminated tuberculosis affecting urogenital system are more fre quent in developing countries but are often overlooked in developed ones. We aimed to compare clinical characteristics and outcomes of urogenital tuberculosis and disseminated tuberculosis affecting the urogeni tal system.

Material and methods: We retrospectively reviewed data from patients with tuberculosis in the urogenital system, diagnosed in a tertiary center in a European country, from 2008 to 2018. Cases were divided into urogenital tuberculosis and disseminated tuberculosis affecting the urogenital system and compared.

Results: We included 172 patients, 31 with urogenital tuberculosis and 141 with disseminated tuberculosis affecting urogenital system. Patients with disseminated tuberculosis affecting the urogenital system were younger (median 45 vs. 64 years, P=.001), more likely to be male (80 vs. 55%, P=.005), or having risk fac tors for the disease (84 vs. 23%, P=.005) than patients with urogenital tuberculosis. Patients with urogenital tuberculosis presented most commonly with symptoms related to the urinary tract, with 52% complaining of lower urinary tract symptoms attributed to urinary tract infections and 48% of dysuria, while patients with disseminated tuberculosis affecting the urogenital system presented mainly with systemic symptoms, with 89% complaining of malaise, 62% of fever, and 57% of anorexia. Patients with urogenital tuberculosis were more likely to need urological surgery as part of their treatment (71 vs. 5%, P < .001) and patients with dis seminated tuberculosis affecting the urogenital system were more likely to die due to tuberculosis (10 vs. 21%, P < .001).

Conclusion: Tuberculosis of the urogenital system can have multiple clinical presentations, and a simple diagnostic algorithm does not exist. In the presence of urogenital tuberculosis in injected drug users, immu nosuppressed individuals, or patients with systemic symptoms, we should think of disseminated tuberculosis affecting the urogenital system and remember these patients less frequently need surgery but entail a worst outcome.

Sufficient functional repair of damaged peripheral nerves is a big clinical challenge in terms of long-lasting morbidity, disability, and economic costs. Nerve damage after radical prostatectomy is the most common cause of erectile dysfunction. In recent years, low-intensity extracorporeal shockwave therapy has been explored to improve the outcomes of peripheral nerve repair and regeneration. Research indicated that application of low-intensity extracorporeal shockwave therapy after nerve surgery promoted nerve regeneration and improved the functional outcomes, underlined the mechanisms related to increase of neurotrophic factors, Schwann cells activation, and cellular signaling activation for cell activation and mitosis induced by low-intensity extracorporeal shockwave therapy. We searched PubMed for articles related to research on these topics in both in vitro and in vivo animal models and found numerous studies suggesting that the application low-intensity extracorporeal shockwave therapy could be a novel treatment for erectile dysfunction induced by nerve injury and other disease related to nerve injury.

Artificial intelligence is used in predicting the clinical outcomes before minimally invasive treatments for benign prostatic hyperplasia, to address the insufficient reliability despite multiple assessment parameters, such as flow rates and symptom scores. Various models of artificial intelligence and its contemporary applications in benign prostatic hyperplasia are reviewed and discussed. A search strategy adapted to identify and review the literature on the application of artificial intelligence with a dedicated search string with the following keywords: "Machine Learning," "Artificial Intelligence," AND "Benign Prostate Enlargement" OR "BPH" OR "Benign Prostatic Hyperplasia" was included and categorized. Review articles, editorial comments, and non-urologic studies were excluded. In the present review, 1600 patients were included from 4 studies that used different classifiers such as fuzzy systems, computer-based vision systems, and clinical data mining to study the applications of artificial intelligence in diagnoses and severity prediction and determine clinical factors responsible for treatment response in benign prostatic hyperplasia. The accuracy to correctly diagnose benign prostatic hyperplasia by Fuzzy systems was 90%, while that of computer-based vision system was 96.3%. Data mining achieved sensitivity and specificity of 70% and 50%, respectively, in correctly predicting the clinical response to medical treatment in benign prostatic hyperplasia. Artificial intelligence is gaining attraction in urology, with the potential to improve diagnostics and patient care. The results of artificial intelligence-based applications in benign prostatic hyperplasia are promising but lack generalizability of results. However, in the future, we will see a shift in the clinical paradigm as artificial intelligence applications will find their place in the guidelines and revolutionize the decision-making process.
