RESUMO
Background: Urethroplasty is the gold standard treatment procedure for male patients with urethral stricture and is becoming increasingly popular among urologists worldwide. Procedure success rates have risen with increased experience. Aims: Here we aimed to examine the results of urethroplasty in challenging cases of urethral stricture and its effect on sexual function. Patients and Methods: Data were collected retrospectively from the patients who had undergone urethroplasty after multiple failed direct vision internal urethrotomy (DVIUs) from 2017 to 2020. All patients were monitored for a minimum of 12 months. Outcomes of urethroplasty were analyzed according to stricture location, length, and the number of prior DVIUs. Penile length and sensation, erectile, and ejaculatory function of the patients were evaluated pre- and postoperatively. Results: The patient cohort consisted of 36 males with a mean age of 63 ± 3.2 years. The most prevalent stricture etiology was iatrogenic (83%). Patients who underwent three or more DVIUs before urethroplasty and stricture length >4 cm were included in the analysis. Accordingly, the overall success rate was 83% (30/36). When the success rate and the IIEF5 scores were assessed separately, there was no significant relationship between the number of DVIUs (P > 0.05). Similarly, no significant relationship was also found with the stricture length (P > 0.05). Conclusion: Appropriate and correctly applied surgical technique does not impair sexual activity, even in patients with severe urethral stricture, regardless of the length or location of the stricture and the number of prior endoscopic procedures.

INTRODUCTION: CIP2A is an oncoprotein involved in the progression of several human malignancies. It has recently been described as a prognostic marker in many cancers. The present study aimed to investigate the immunohistochemical expression of CIP2A in benign prostatic hyperplasia (BPH), high grade prostatic intraepithelial neoplasia (HGPIN) and prostate cancer (PC), and to analyse the association with the clinicopathological parameters in PC cases to define its role in the development and progression of PC. MATERIALS AND METHODS: Immunohistochemical staining for CIP2A was performed on the tissue microarray sections of 105 PC, 27 HGPIN and 27 BPH tissues. The CIP2A expression scores were compared with several clinicopathological parameters. RESULTS: CIP2A was expressed in 96,2% of PC, 55,6% of HGPIN and 40,7% of BPH tissues. The expression of CIP2A in PC was significantly higher than in HGPIN (p<0.0001) and BPH (p<0.0001) cases. CIP2A expression score was significantly associated with Gleason score (p=0.032) and lymphovascular invasion (p=0.039). Nevertheless, there was no statistically significant association between the expression of CIP2A and perineural invasion, pT stage, metastasis and recurrence (p>0.05). Multivariate analysis indicated that GS, lymphovascular invasion, distant metastasis were independent prognostic factors for PC patients but, CIP2A expression score was not found to be a prognostic factor. Additionally, there was no significant difference between the survival times of patients according to CIP2A expression (p=0.174). CONCLUSIONS: According to our results, the expression of CIP2A protein is increased in PC and its expression may be involved in the development, differentiation, and aggressiveness of PC. However, further studies are needed to confirm our findings and to clarify the role of CIP2A in the development of PC.

OBJECTIVES: The aim of the present study was to assess whether the use of platelet-rich fibrin (PRF) decreased the pain, swelling, and trismus levels of postoperative third molar surgery. MATERIALS AND METHODS: In a double-blinded, split-mouth randomized study, thirty patients (6 male/24 female, mean age 20.32 years) with bilateral symmetric impacted third molars were enrolled in this study to receive surgery. The PRF mass was randomly placed in one of the extraction sockets, whereas the other socket was left without treatment. The outcome variables were pain, maximum mouth opening (trismus), swelling (edema), and the presence of dry socket which were measured using a 10-point visual analog scale, manual calipers, and 3dMD facial imaging system which was used for the 1st time in the third molar surgery. RESULTS: Statistical analyses revealed that there were no significant differences between the control and study groups regarding postoperative pain, swelling, and trismus (P > 0.05). CONCLUSION: The results of this study suggest that PRF was not observed to have a positive effect on postoperative discomfort, so even though, PRF is presumed to have positive effects on healing and recovery processes.
