RESUMO
A 48-year-old man admitted to the urology outpatient clinic with major symptoms of right-side pain and intermittent lower urinary tract symptoms (LUTSs) such as low urine flow rate, dysuria, and frequency. Uroflowmetry showed low urine flow, and laboratory tests revealed no pathology. Ultrasound (US) showed a 7 cm calcific mass above the bladder and a kidney cyst with a diameter of 5.3 cm in the upper pole of the right kidney. Enhanced computed tomography confirmed the US findings. Laparoscopic transperitoneal renal cyst decortication was performed. There was no sign of additional tumors. An independent mass in the abdomen was diagnosed, and the mass was removed. Based on the pathology, the diagnosis was a benign mesenchymal calcific mass. This is the first report of LUTSs due to a free benign mesenchymal mass in the published literature.
RESUMO
OBJECTIVE: To introduce a novel endoscopic surgical technique with mini-nephroscope by suprapubic transvesical route for cystolithotripsy in children. MATERIAL AND METHODS: This was a non-randomized study with a series of 12 boys, between February 2012 and September 2013. Demographic, operative, and postoperative data were recorded. Our new endoscopic surgery technique could be performed in all patients. Complications were noted. RESULTS: Mean age was 35.1 ± 8.6 months (19-46 months), the average stone size was 16.5 ± 5.2 mm (10-20 mm). Mean operation time was 28.9 min (21-40), and mean hospital stay was 2.2 (2-3) days. In all procedures, stones were successfully fragmented and extracted by the new surgical technique. There was no intraoperative and/or postoperative complication or urethral stricture during follow-up period. In stone analyses, the main components were ammonium acid urate, calcium oxalate, and struvite. CONCLUSIONS: The new endoscopic surgery technique is safe and effective for bladder stones in children. Thus, our technique can be a strong candidate for an alternative treatment of childhood bladder stones.
