Management of Priapism: Results of a Nationwide Survey and Comparison with International Guidelines

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.

Biopsy with Ureterorenoscopy Before Radical Nephroureterectomy is Associated with Increased Intravesical Recurrence in Urothelial Cancer Located in the Kidney

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.

Failure of ureteral access sheath insertion in primary flexible ureteroscopy for renal stones: is there any relation with inflammation?

PURPOSE

To investigate the relationship between failure to insert a ureteral access sheath (UAS) with inflammation and other clinical parameters in patients treated with flexible ureteroscopy for renal stones.

METHODS

This study included patients who underwent flexible ureteroscopy for the treatment of renal stones in our centre between 2015 and 2020. Patients who underwent any surgical procedure on the ipsilateral ureter and had a history of spontaneous stone passage were excluded. Patients were divided into two groups based on UAS insertion success (group 1) or failure (group 2). Both groups were compared with a view to clinical characteristics, preoperative neutrophil, lymphocyte, monocyte and platelet counts and ratios of these counts, all being considered inflammatory markers. A multivariate logistic regression analysis was performed to determine the independent variables affecting UAS insertion success.

RESULTS

There were 113 (59.1%) patients in group 1, while group 2 consisted of 78 (40.9%) patients. The rates of male gender, coronary artery disease and preoperative ipsilateral hydronephrosis were significantly higher in group 2, while platelet counts and platelet-lymphocyte ratios were significantly lower. Our analysis revealed four independent predictors for UAS insertion failure: female gender (odds ratio [OR]=2.1) increased the rate of UAS insertion success, while hydronephrosis (OR=1.6), low platelet counts and PLR increased the rate of UAS insertion failure (OR=0.99, OR=0.98, respectively).

CONCLUSION

Our results suggest that male gender and ipsilateral hydronephrosis are associated with increased UAS insertion failure. Although we found a relationship between relatively low platelet levels and UAS insertion failure, we think that further studies are needed to investigate this matter.

The fate of paratesticular masses: 13 years' experience in a tertiary referral centre

OBJECTIVE

Paratesticular neoplasms exhibit different behaviours, depending on the embryological tissue of origin. Treatment modalities can depend on the differential diagnosis. The aim of this study is to present the clinical, morphological and histopathological features of patients with paratesticular masses and their follow-ups and is intended to increase awareness of the issues.

METHODOLOGY

We included 31 excisions of paratesticular masses, after radiological diagnosis as paratesticular mass in our hospital between 2007-2020. Information on treatment modalities, tumour recurrence, metastasis, and survival rates were obtained from hospital archives. All patients were evaluated by taking patients' history, physical examination, scrotal ultrasound, chest radiography, and serum tumour markers. Treatment modality was selected according to intraoperative findings. Haematoxylin-eosin sections were examined, and immunohistochemical analyses were performed for smooth muscle actin, desmin, Ki67, CD34, S100, and myogenin. Ten high-power fields were counted to document Ki67 and p53 nuclear positivity rates.

RESULTS

A total of 31 operations were performed with recurrence in three patients. Histomorphological and immunohistochemical examination revealed eleven malignant masses; eight rhabdomyosarcomas, a leiomyosarcoma, a liposarcoma and a large B cell lymphoma. Other excised masses were benign and infective lesions.

CONCLUSION

Paratesticular masses are heterogeneous tumours that follow different clinical courses. Clinicians must be aware of this histological diversity in order to plan a treatment pathway. This study is one of the largest published series, with a long follow-up period. It shows that the most critical features in determining prognosis are histopathological subtype and tumour grade.

Preputial bacterial colonisation in uncircumcised male children: Is it related to phimosis?

OBJECTIVE

To evaluate the presence of uropathogens in the periurethral skin and the effect of phimosis on bacterial colonisation.

METHODS

The observational cohort study was conducted in Samsun Research and Training Hospital, Samsun, Turkey from June to December, 2014, and comprised patients undergoing circumcision. Before circumcision, all children were examined in the operating room and the presence of phimosis was recorded. All patients had circumcision performed by the same surgical team under general anaesthesia. Before the procedure, samples were taken from preputial skin of all patients by swab before cleansing with polyvidone-iodine. The samples were inoculated on 5% sheep blood agar and eosin-methylene blue agar.

RESULTS

The median age of the 117 children was 5 years (range: 1-12). Of the total, 19(16.2%) children had complete phimosis, and 72(61.5%) had partial phimosis. In all,91(77.7%) children had phimosis and 26(22.3%) had no phimosis. Of the 91 patients with different degrees of phimosis, 52(57.1%) had clinically significant uropathogenic bacterial colonisation >100,000 colony-forming units per millilitre [cfu/ml]). Of the 26 patients without phimosis, 13(50%) had clinically significant colonisation. Thus, there was no effect of the presence of phimosis on bacteria colonisation (p=0.655).

CONCLUSIONS

Important uropathogens colonise the preputium in uncircumcised male children. There was no effect of phimosis on colonisation.
