Aim Bladder cancer is the second most common urological malignancy after prostate cancer. Increase in the post-void residual (PVR) volume may result in an increase in the risk of cancer recurrence. Methods Patient demographic data, tumor stage and grade, PVR volume and 2 years follow-up data for recurrence were obtained and evaluated. Results One-hundred-and-nineteen patients were subdivided into three groups according to PVR urine volume. The increase of PVR volume was related to short recurrence-free survival (RFS) especially for patients with PVR volume of 60 ml or more. Conclusion Low PVR volume in patients with non-muscle invasive bladder cancer may play a role in reducing cancer recurrence. However further research is needed in this field.

Does post-void residual urine volume affect potential recurrence risk for non-muscle invasive bladder cancer?

[Dislocation of the distal radioulnar joint with rotation block].


 Background Traumatic isolated dislocation of the distal radioulnar joint (DRUJ) has always been an injury recognized for its rarity, misdiagnosis, and possibility of inability to be reduced at emergency care. As a result, little has been discussed so far about the guidelines and routines for its treatment.It is known that some degree of injury to the triangular fibrocartilage (TFC) is required for a DRUJ to be dislocated. However, there is no evidence to prove that this injury will cause any degree of DRUJ instability following reduction.
 Methods We show a case of a patient with traumatic isolated volar dislocation of the DRUJ in which, after failure in the attempt to reduce it in the emergency room, surgical treatment was performed using an arthroscopic method.
 Results Computed tomography and magnetic resonance imaging axial sections showed the impaction of the distal ulna, with its groove to the extensor carpi ulnaris tendon blocked in the anterior labrum of the sigmoid notch of the radius. Arthroscopy before reduction showed that the distal portion of the TFC was intact, with damage to the foveal insertion (Palmer Type 1B, Atzei Class 3). After joint reduction, a loop-shaped repair of the TFC foveal lesion was performed through the central disc and attached to the distal ulna footprint. The patient presented good progression, with quick recovery, and no serious complications or the need for a second surery.
 Conclusion We indicate the use of arthroscopy in patients with irreducible isolated volar dislocation, with subacute or chronic presentation, who have to be managed in the operating room. It is a useful method for diagnosing and repairing the TFC injury. This will prevent possible complications and provide faster recovery, mainly reducing the time of immobilization.

Arthroscopic Treatment of Traumatic Isolated Volar Dislocation of the Distal Radioulnar Joint: Case Report and Management Proposal

Introduction: Isolated acute distal radioulnar joint (DRUJ) dislocation is a rare condition and easy undiagnosed. Few cases are reported in the literature about its treatment. We reported a case of an isolated acute traumatic dorsal DRUJ dislocation treated with early reduction and immobilization. Case Report: We present a case of a 12-year-old female with an isolated dorsal acute DRUJ dislocation. We performed for the early diagnosis a clinical examination, X-rays, and computed tomography scan. We treated this condition with a closed reduction and immobilization in an above-elbow cast for 4 weeks and in a below-elbow brace for 2 weeks. The outcome was good. Conclusion: Isolated acute dorsal DRUJ dislocation is an uncommon injury; the early diagnosis and timely treatment usually result in good outcome. In our case, an early transition to below-elbow brace results in a faster recovery. Keywords: Isolated dorsal distal radioulnar joint dislocation, closed reduction, case report.

Case report: Isolated acute dorsal distal radioulnar joint (DRUJ) dislocation

Introduction: Intravesical chemotherapy instillation by mitomycin - C (MMC) immediately after transurethral resection of bladder tumor (TURBT), although effective in reducing the incidence of non- muscle invasive bladder cancer (NMIBC) recurrence, can result in non desirable effects like bladder irritation and hematuria . Continuous bladder irrigation with saline post resection has been studied as an alternative. In our study we compare the rates of NMIBC recurrence and progression in patients who were treated with either MMC or CSBI immediately after tumor resection. Methods: We retrospectively reviewed the medical records of patients with NMIBC at our institution in Jordan university hospital in the period between 2015-2019. Postoperative instillation of MMC or CSBI for four hours was recorded. Follow up of the patients for recurrence or progression in the first 2 years after diagnosis was recorded and compared for both groups. Results: One hundred nineteen patients met inclusion criteria. Fifty four patients received MMC and 65 patients received CSBI immediately post TURBT. Kaplan–Meieranalysis for recurrence- free survival and progression- free survival didn’t show a significant difference between both groups with P- value 0.88 and 0.14 respectively. Conclusion: Postoperative CSBI for four hours following tumor resection is equivalent to immediate postoperative MMC instillation for NMIBC in terms of recurrence or progression rates with fewer side effects . However further research is needed in this field .
