Penile fracture is a rare urological emergency. It occurs due to the penis being subjected to force during intercourse or other causes. Treatment is usually surgical. Urethral injury accompanies 10–20% of cases. In this case, a complete urethral rupture accompanying a penile fracture is aimed to be presented. A 45-year-old male patient presented to the emergency department with complaints of a snapping sound, pain, and sudden loss of erection during sexual intercourse. After a while, bleeding from the external meatus and inability to urinate were added to his complaints. Physical examination showed typical signs of penile fracture along with urethrorrhagia. The penile doppler ultrasound result was reported to be consistent with a penile fracture and uretral injury. Approximately one hour after presenting to the emergency department, the patient underwent surgery. Considering the possibility of urethral rupture, a urethroscopy was performed before fracture repair, revealing a urethral defect approximately 8 cm proximal to the external meatus. Surgical repair found a near-complete bilateral rupture of the corpus cavernosum and a complete urethral rupture. The urethral rupture and fracture area were repaired according to surgical procedure standards. No additional complaints or new pathologies were observed in the early postoperative follow-up. The patient was discharged with a catheter on postoperative day 3. On the 14th postoperative day, the patient’s catheter was removed. At the 3-month follow-up, the patient had no urinary complaints, and the uroflowmetry test showed a Qmax of 35. No pathology was detected in the urethrography performed. At the one-year follow-up, the patient’s International Index of Erectile Function (IIEF) score was 26, indicating no additional complaints. Complete urethral rupture and bilateral corpus cavernosum rupture are rare urological emergencies, typically resulting from trauma applied to an erect penis. A physical examination, ultrasonography, and, when necessary, imaging techniques such as cystoscopy are the diagnostic modalities employed in such cases. Early surgical treatment has been shown to improve functional outcomes and reduce long-term complications. Early surgical intervention in the treatment of penile fractures not only preserves sexual function but also significantly reduces long-term complications. Urethral rupture should always be considered in fractures accompanied by urethrorrhagia and hematuria.

Active surveillance (AS) is an established strategy for managing low-risk prostate cancer (LRPCa), aiming to reduce overtreatment while maintaining oncological safety. This retrospective cohort study included 102 patients diagnosed with LRPCa between 2015 and 2025, managed with serial prostate-specific antigen (PSA) testing, digital rectal examination, multiparametric MRI (mpMRI), and confirmatory biopsies. Transition criteria included Gleason score upgrading, PSA progression, lesion progression on mpMRI, or patient preference. The median follow-up was 16 months (range: 6–123), while the estimated median surveillance duration was 36 months (95% confidence interval: 30–42). Retention rates at 2 and 5 years were 72% and 50%, respectively. A total of 35.3% (36/102) of patients discontinued AS, most frequently due to patient preference (61.1%), followed by PSA progression (25.0%) and histopathological upgrading (13.9%). Only 25.5% (26/102) of patients underwent confirmatory biopsy during follow-up, reflecting suboptimal adherence that may have contributed to an underestimation of true pathological progression. Multivariate analysis revealed that higher final PSA levels (odds ratio [OR]: 1.559, P = .001), abnormal digital rectal examination findings (OR: 11.079, P < .001), and Prostate Imaging-Reporting and Data System 4 to 5 lesions on mpMRI (OR: 5.482, P < .001) were independently associated with transition to definitive treatment. These findings suggest that AS remains a feasible and effective management strategy for LRPCa, though confirmatory biopsies and structured psychological support are essential to optimize adherence and prevent overtreatment. Future studies should investigate the integration of biomarkers and AI-assisted imaging in refining AS protocols.

Background. Systemic oxidative stress may cause detrimental consequences for the liver, leading to hepatic fibrogenesis. Objectives. To investigate histopathological changes in liver tissues due to the increased systemic oxidative stress associated with rat extracorporeal shock wave lithotripsy (SWL) model and to document the consequences of N-acetylcysteine (NAC) administration. Material and methods. In this experimental SWL model, 18 Wistar albino rats were randomly assigned into 3 groups. The control group (group I) had no intervention. Group II underwent SWL treatment with intraperitonea I saline injection. Group III also had SWL with intra peritoneal NAC and was divided into short-term (group III-14 days) and long-term (group III-28 days) subgroup. Hepatectomy was performed for histopathological examinations. Histopathological alterations were evaluated with light microscopy. Immunohistological staining for p53 and myeloperoxidase was also performed. Results. Blood samples revealed a significant increase in plasma oxidative stress index (OSI) after plasma total antioxidant status (TAS) and total oxidant status (TOS) had been measured. It was shown that this increased systemic oxidative stress adversely affected liver tissues. Predominantly, sinusoidal dilatation was remarkably observed in rats with significantly high 051 values (p = 0.043). Similarly, periportal necrosis significantly increased in rats with high OSI values (p = 0.033). p53 positivity was also remarkable in rats with systemic oxidative stress (p = 0.049). N-acetylcysteine administration provided a significant decrease in OSI. N-acetylcysteine also improved all these alterations, including p53 staining. Particularly, sinusoidal dilatation was significantly protected in the long-term NAC group (group III-28 days). Conclusions. We demonstrated that SWL-induced systemic oxidative stress causes histological alterations in liver tissues. Increased p53 and myeloperoxidase staining as markers of oxidative damage were also detected. N-acetylcysteine may protect from these histological and ultra-structural alterations related to oxidative stress.

Urinary stone disease is a common urological disorder, particularly among middle-aged individuals. Extracorporeal Shock Wave Lithotripsy (ESWL) is often the first-line treatment for kidney and ureteral stones. Traditionally, fluoroscopy is used for stone targeting in ESWL, but it exposes patients and clinicians to radiation and cannot visualize non-opaque stones. Ultrasonographic targeting eliminates these issues. This study compares the advantages and disadvantages of fluoroscopy and ultrasound-targeted ESWL. At Düzce University Hospital, 100 patients with radio-opaque stones indicated for ESWL between February 2023 and February 2024 were divided into two groups. Group A underwent ESWL with fluoroscopic targeting, while Group B used ultrasonographic targeting. Patient demographics, stone size (measured by CT), and stone locations were recorded. The number of shocks per session, energy intensity (kV), and fluoroscopy time were noted for Group A. One week after each ESWL session, patients were evaluated by ultrasound or direct radiography. Success was defined as being stone-free or having ≤ 4 mm asymptomatic residual stones after up to four sessions. Failure was defined as no results after two sessions or the need for additional treatment. The procedure success rate was 66% for men and 78% for women, with no statistically significant gender difference (p > 0.05). Stone locations were similar in both groups. Success rates were 66% in Group A and 74% in Group B, with no significant difference (p > 0.05). Successful procedures were associated with an average patient weight of 76.6 kg, stone size of 8.9 mm, and total energy of 12.2 kV, with significant differences compared to unsuccessful procedures (p < 0.04, p < 0.04, p < 0.001, respectively). No significant differences were found between Group A and Group B in terms of age, height, BMI, stone density (HU), and number of sessions (p > 0.05). Ultrasonography is as effective as fluoroscopy for imaging and focusing during ESWL treatment. It enhances the success of ESWL for non-opaque stones and reduces radiation exposure disadvantages.

Aim: This study aimed to compare the effects of supine and prone positions during percutaneous nephrolithotomy (PCNL) on operative characteristics, patient out-comes and postoperative quality of recovery. Material and Methods: A retrospective analysis was conducted on 78 patients who underwent PCNL for renal stones ≥2 cm at a single center between December 2022 and August 2024. Patients were divided into two groups: 41 treated in the mini-PCNL (mPCNL) supine position and 37 in the standart PCNL (sPCNL) prone position. Demographic data, operative time, hospital stay duration, complication rates, postoperative pain and analgesic requirements and quality of recovery scores (QoR) were compared. Treatment efficacy was assessed based on residual stone presence at 2 months postoperatively, with
