ABSTRACT
Bladder noninvasive squamous lesions are usually rare; here, we are presenting a case of 39 years old male patient with a benign squamous cell papilloma. The tumor grossly presented as cauliflower mass mimicking squamous cell carcinoma, while histologically, the tumor showed extensive keratinization at its surface and showed no nuclear atypia or stromal invasion. This tumor is benign and extremely rare. In this manuscript, we summarized a case of Squamous cell papilloma of the bladder with the first operative video for the transurethral resection of squamous cell papilloma with percutaneous management of associated urinary bladder stones.
ABSTRACT
AIM: Shock wave lithotripsy (SWL) is a well-established modality in the treatment of urolithiasis. Studying the effect of urine pH on SWL success is appealing as pH can be manipulated before SWL to insure a better outcome. MATERIALS AND METHODS: This is a prospective study performed at a tertiary medical center. Patients presenting to the SWL unit with a single renal stone <2 cm in size were included in this study. In addition to standard laboratory and radiologic investigations, urine pH measurement was performed on all patients before their procedure. The number of sessions performed, and the stone-free rate (SFR) were assessed. Patients were divided into two groups according to stone clearance. Group 1 was stone-free, whereas Group 2 had residual stones after three sessions of SWL. Data was also classified according to different pH ranges. Influential factors were compared among the study groups and pH ranges. RESULTS: A total of 175 patients were included in this study. The SFR was 54.3%. The mean number of sessions performed was 2.2 ± 0.8. Group 1 included 95 patients, whereas Group 2 had eighty patients. Among all studied factors, stone size (P = 0.03) and skin to stone distance (P = 0.04) significantly affected SFR with SWL. Urine pH was not found to have a statistically significant influence on SWL outcome (P = 0.51). CONCLUSION: Urine pH was not found in this study population to influence the effectiveness of SWL. Further experimental studies are required to help investigate this notion.
ABSTRACT
Granulosa cell tumours (GCTs) can be either juvenile or adult type, and more commonly occur in the ovaries. Adult-type GCTs of the testis (AGCTT) are very rare and only 46 cases have previously been reported. We report here on a 48-year-old Filipino man with a left testicular AGCTT, which measured 1.2 × 1.2 × 1.0 cm. He underwent radical orchidectomy with postoperative surveillance for 1 year, which included computed tomography with oral intravenous contrast and clinical examinations, which have been unremarkable. The previously reported AGCTTs were briefly reviewed.
ABSTRACT
OBJECTIVE: To evaluate all possible risk factors that can cause impairment of overall renal function in patients with unilateral ureteral calculus and a normal contralateral kidney. METHODS: This is a prospective study of 90 patients who presented to our institute complaining of renal colic secondary to unilateral ureteral calculus. All patients were evaluated with a thorough history, physical examination, and laboratory and radiological investigations including renal function testing, urine analysis, non-contrast computed topography, and radionucleotide scan. Patients were divided into two groups according to their calculated creatinine clearance using the Modification of Diet in Renal Disease (MDRD) formula. Group I (favorable group) had a creatinine clearance >60 ml/min, while group II (unfavorable group) had a creatinine clearance <60 ml/min. RESULTS: The patients' mean age ± SD was 38.8 ± 11.4 years. Group I included 54 patients (60 %), while group II included 36 patients (40 %). On univariate analysis, factors that were associated with overall renal function impairment were patients' age, urea-to-creatinine ratio (UCR), use of nonsteroidal anti-inflammatory drugs, stone location, and presence of obstruction. However, using binary logistic regression analysis, only patients' age, UCR, and presence of obstruction sustained statistical significance in association with renal function impairment. CONCLUSION: The study of factors that help explain the presence of renal impairment in patients with unilateral ureteral calculus is important in the clinical setting. Patients' age, urea-to-creatinine ratio, and degree of obstruction seem to be significantly associated with overall renal function impairment.
