    Abstract The prognostic significance of the platelet-lymphocyte ratio (PLR) in nonmetastatic renal cell carcinoma (RCC) is controversial, although it has been established as a prognostic factor in several cancers.
    Objective: The objective of our study was to evaluate the prognostic significance of the PLR in patients with nonmetastatic RCC.
    Patients and methods: The authors performed a retrospective analysis of patients with nonmetastatic RCC who were operated between 2004 and 2020. Five years recurrence-free survival and metastasis-free survival were calculated. The prognostic significance of the preoperative PLR was assessed. The Kaplan-Meier method was utilized to graphically display survivor functions. Univariate and multivariate Cox's proportional hazards regression models were utilized to analyze the association between PLR and oncological outcomes. Differences were considered significant if
    Results: Two hundred and two patients were included. The mean follow-up was 56.8±3 months. Patients with a higher PLR had larger tumors (
    Conclusion: A higher PLR was associated with aggressive renal cancer. In addition, the PLR was a significant prognostic factor for both recurrence-free survival and metastasis-free survival in patients with nonmetastatic RCC.

    Abstract Hydatid cyst is a major health problem in developing countries. The kidney is in third position of organs affected by hydatid cyst. One of the complications of renal hydatid cyst is a urinary fistula. The purpose of this study is to identify preoperative predictive factors of urinary fistula in renal hydatid cyst and to develop a scoring system for this disorder. We retrospectively analyzed all patients operated for renal hydatid cysts between January 2000 and December 2020. We divided our patients into two groups according to whether or not the renal hydatid cysts opened in the urinary tract. Predictive factors of the presence of a urinary fistula have been studied to obtain a simple score to predict the presence of a urinary fistula. Differences were considered significant if p < 0.05. Urinary fistula was detected in 33 of 96 patients. Univariate analyses showed significant differences in patient age, cyst size, location, hydaturia, eosinophil count, and platelet count between patients with and without urinary fistula. In multivariate analyses, hydaturia (p < 0.005), eosinophil count >500/mm

    Abstract Introduction: The main problem after Radical Nephroureterectomy (RNU) for localized non-metastatic upper urinary tract urothelial cancer (NM-UUT-UC) is bladder recurrence.
    Aim: To identify factors of bladder recurrence of localized NM-UUT-UC after radical treatment.
    Methods: It is an analytical and observational study that was conducted in the department of urology of La Rabta Hospital in Tunis. We collected the data of patients diagnosed with localized NM-UUT-UC who had RNU between 2005 and 2019.
    Results: The mean age of the 73 eligible patients was 68 years (±11). The sex ratio was 5/2. Macroscopic hematuria was the revealing clinical sign in 66% of patients, while low back pain was the most frequent sign in 88% of patients. The most frequent tumor stage was pT1 in 20 patients while 32% of them had a pT2-T3 stage. Bladder recurrence was reported in 22% of patients with a median time of nine months [4-27] and extremes of three and 69 months. Factors of bladder recurrence in the univariate analysis were smoking, tumor localization in the ureter and the extravesical excision of the intramural ureter and bladder cuff. On multivariate analysis, the only independent predictor of bladder tumor recurrence was ureteral location (OR=3.65; CI95%=[1.02-13.1]

    p=0.047).
    Conclusion: Tumor localization in the ureter was an independent predictor of bladder recurrence after radical treatment for localized NM-UUT-UC.

    Abstract Ocular abscess following transurethral resection of the prostate is an rare complication. We report the case of a male who developed an ocular abscess with purulent melting of the eye after undergoing TURP for benign prostatic hyperplasia. The patient successfully underwent the TURP procedure. However, he developed a right epididymitis and subsequently an ocular abscess on the same side. Treatment involved dual antibiotic therapy for the epididymitis, followed by incision of the ocular abscess and intravenous antibiotics. Multidrug-resistant

    Abstract Emphysematous prostatitis is characterized by their rarity and its severity. It often occurs in older diabetics. This study reports a new case of an isolated emphysematous prostatitis in a 66-year-old patient which presented with mental confusion and severe sepsis. Computed tomography revealed intra parenchymal air bubbles of the prostate which evolved well after early resuscitation and rapid and effective antibiotic therapy. Emphysematous prostatitis is an uncommon but potentially serious disorder that has the potential for causing problems if not diagnosed at the early stage and treated promptly.

    Abstract Having a kidney disease is a major risk factor of renal injury during blunt traumas. We present a case of abdominal blunt trauma due to motor-vehicle accident in a 48 year old male patient. Abdominal computed tomography scan showed a high-volume retroperitoneal hematoma with rupture in the isthmus of the horseshoe kidney with active contrast-enhanced extravasation. He underwent a partial nephrectomy of the left lower pole.

    Abstract Urinary tract endometriosis (UTE) is a very rare but serious form of infiltrating endometriosis because of the risk of urinary tract obstruction and loss of renal function. We report the case of A 42-year-old female patient admitted for intense right back pain with lower urinary tract disorders. An abdomino-pelvic ultrasound was done showing right uretero-hydronephrosis. Ureteroscopy showed an inflammatory-like stenosis of the right pelvic ureter. Given the young age of the patient, the poor quality of the right kidney, we opted for a right total nephro ureterectomy. The anatomopathological examination showed a bladder endometriosis

    Abstract Sarcomas are uncommon and extremely aggressive malignancies. Sarcomas of the bladder are exceedingly rare. We report the case of 67-year-old female patient having had 20 years ago a total hysterectomy with bilateral adnexectomy followed by adjuvant external radiotherapy to an undifferentiated uterine sarcoma, was presented with hematuria. An abdomino-pelvic Computed Tomography (CT) Scan was done showing a 5 cm budding lesion of the bladder floor. An anterior pelvectomy with external urinary diversion was undergone. The histological examination showed a high grade urothelial carcinoma infiltrating the muscle with a sarcomatoid component.

    Abstract Background: Angiomyoma is a rare benign tumor that can occur in any organ with smooth muscles. No one has already described an angiomyoma of the ureter.
    Case presentation: We report the case of a 44 year old woman who presented with intermittent hematuria and left flank pain. The diagnosis of left ureteral tumor was evoked by the scannographic aspect. She underwent a radical nephro-ureterectomy. Final histological examination concluded to ureteral angiomyoma.
    Discussion: Angiomyoma is rare benign smooth muscle tumor with a vascular component. Symptomatology depends on the organ that angiomyoma is developed from, and is usually mimicking malignant tumors.
    Conclusion: Symptomatology, radiologic findings are mimicking urothelial carcinomas, however the pathology corrected the diagnostic error.
