It was aimed to investigate the efficiency and reliability of the manual detorsion (MD) procedure in patients diagnosed with testicular torsion (TT). A retrospective analysis was made of the data of 57 patients diagnosed with TT, comprising 20 patients with successful MD (Group I), 28 patients who underwent emergency orchiopexy (Group II), and 9 patients applied with orchiectomy (Group III). The groups were compared in respect of age, and duration of pain. The success rate of MD, the time of testicular fixation (TF), any problems encountered in follow-up, and follow-up times were analyzed in Group I. Data were analyzed with P-P pilot, Mann-Whitney U, Kruskal Wallis and Chi-square tests. A value of p < 0.05 was considered statistically significant. MD was successful and detorsion could be achieved in 20 of 26 patients. The groups were similar in respect of age (p = 0.217). The median duration of pain was 3 (1–8), 4 (1–72), and 48 (12–144) hours in Groups I, II, and III, respectively, and determined as similar in Groups I and II (p = 0.257), although a statistically significant difference was determined between the 3 groups (p < 0.001). TF was applied to Group I after median 10 (0–45) days, and no parenchymal disorder was determined in the median follow-up period of 21.5 (2–40) months. MD that can be easily and immediately performed after the diagnosis of TT decreases ischemia time. This seems to be an efficient and reliable procedure when applied together with elective orchiopexy, as a part of the treatment.

Objective: The aim of this study is to evaluate current urologic practice regarding the management of priapism in Turkey and compare with international guidelines. Methods: Urologists and urology residents were invited to an online survey consisting of 30 multiple-choice questions on priapism-related clinical practices that were consid- ered most important and relevant to practices by using Google Forms. Results: Total number of responses was 340. Respondents reported that they recorded a detailed patient’s medical history and physical examination findings (n = 340, 100%) and laboratory testing, which includes corporal blood gas analysis (n=323, 95%). Participants announced that they performed Doppler ultrasound for 1/4 cases (n = 106, 31%), but 22% of the participants (n=75) replied that they performed in >75% of cases. Participants (n=311, 91%) responded that the first-line treatment of ischemic priapism is decompression of the corpus cavernosum. Moreover, most respondents (n = 320, 94%) stated that sympathomimetic injection drugs should be applied as the second step. About three-quarters of respondents (n = 247, 73%) indicated adrenaline as their drug of choice. Phosphodiesterase type 5 inhibitors seems to be the most pre- ferred drug for stuttering priapism (n=141, 41%). Participants (n=284, 84%) replied that corpora-glanular shunts should be preferred as the first. A large number of par- ticipants (n = 239, 70%) declared that magnetic resonance imaging can be performed in cases with delayed (>24 hours) priapism to diagnose corporal necrosis. Most of the participants (84%) responded that penile prosthesis should be preferred to shunts in cases with delayed (>48 hours) priapism. Conclusion: It would be appropriate to improve the training offered by professional associations and to give more training time to the management of priapism during residency.
