Background: A ureteral diverticulum (UD) is a rare urological malformation characterized by the saccular enlargement of the ureteral wall. It can be of different sizes and in various localizations. In the literature, three types of UD have been defined as abortive bifid ureter, congenital, and acquired. Case Report: In a 65-year-old male patient, an enlargement was incidentally detected in the distal part of the right ureter on fluoroscopy during the passage of the contrast agent applied during angiography. The medical history of the patient was not remarkable; thus, computed tomography (CT) was performed to investigate the etiology. A dilated tubular structure separate from the ureter was observed in the middle part of the right ureter on CT, clearer in the excision phase. This tubular structure distally connected with ureter and was consistent with the abortive bifid ureter type of UD. Discussion: UD may present with renal colic, hematuria, and upper urinary tract infections, or it may be asymptomatic as in our case. Asymptomatic cases are usually incidentally detected during radiological imaging. Although treatment is not required for these patients, surgical treatment may be required in the presence of symptoms. Conclusion: UD is an entity that can be asymptomatic until adulthood and may be detected incidentally in radiological evaluations. UD should be kept in mind when the cystic lesion associated with the ureter is detected in radiological examination. Excretory phase CT / CT urography noninvasive imaging method must be preferred in to evaluate the relationship of the lesion with the ureter.

Objective: The present study examines the effects of the coronavirus disease 2019 pandemic on radical prostatectomy performed as part of localized prostate cancer treatment in Turkey. Material and methods: A retrospective analysis was made of the data of 176 patients from 8 centers in Turkey who underwent radical prostatectomy due to localized prostate cancer over the 2 years spanning March 1, 2019, to February 28, 2021. Within this timeframe, March 1, 2019, to February 28, 2020, was denoted the 1-year pre-coronavirus disease 2019 period, while March 1, 2020, to February 28, 2021, was denoted the 1-year coronavirus disease 2019 period. An analysis was made of whether there was a difference in the number of radical prostatectomies performed for prostate cancer, the time from biopsy to operation, and the biopsy and radical prostatectomy pathology between the 2 periods. Results: It was found that the number of radical prostatectomies performed for localized prostate cancer during the coronavirus disease 2019 pandemic was statistically and highly significantly fewer than in the pre-coronavirus disease 2019 period (P <.001). The patients diagnosed with Gleason 3+3 (low risk) prostate cancer were statistically significantly fewer in number in the coronavirus disease 2019 period (P <.001). The pathological Gleason score was upgrading than the biopsy Gleason score in all patients who underwent in both periods (P <.001). When the periods were compared, the pathological involvement determined by lymph node dissection performed during radical prostatectomy was found to be decreased in the coronavirus disease 2019 period, although the difference was not statistically significant (P =.051). Conclusion: As with many diseases, the diagnosis and treatment of prostate cancer have been adversely affected by the coronavirus disease 2019 pandemic.

There are a few types of drugs that can be used in the active phase of Peyronie's disease. Methylprednisolone is a corticosteroid with a strong anti-inflammatory effect. In this study, we aimed to evaluate the effect of intralesional low-dose methylprednisolone treatment on patients in the active phase of Peyronie's disease. Forty-eight patients suffering from Peyronie's disease active phase symptoms were included in the study. Methylprednisolone was administered intralesionally for 8 weeks, once per week, at a dose of 40 mg. The injection was applied to the plaques, which causes maximum curvature. Patients were evaluated before and after treatment for plaque size, angle of curvature, and erectile dysfunction according to the International Index of Erectile Function-5 and Peyronie's Disease Questionnaire. The mean age of the patients was 61.1 (43-78) years. The mean duration of the symptoms was 3.4 (0-9) months. The average plaque size before treatment was 13.6 mm (7.1-16.8) and after treatment, this value decreased to 10.8 mm (4.3-14.6) (P: .025). The average scores of Peyronie's Disease Questionnaire elements; symptom severity, penile pain, and bother/discomfort were 12.3, 19.1, and 6.2, respectively, before the treatment. These scores were decreased to 8.9, 9.6, and 4.4, respectively, after treatment. All subgroups of Peyronie's Disease Questionnaire scores were significantly improved after treatment (P: .001, P < .001, P: .045, respectively). No adverse events were observed during or after treatment. In order to recover the symptoms and signs, new and easily accessible drugs are required for use in the acute period of Peyronie's disease. In this context, treatment with intralesional low-dose methylprednisolone in acute phase Peyronie's Disease is a promising and safe treatment option.
