1/4. Case report: holmium laser resection and lasertripsy for intravesical ureterocele with calculus.The holmium laser has established an important role in urology, particularly in the treatment of benign prostatic hyperplasia (BPH) and urolithiasis. Its light (wavelength 2140 nm) has a high coefficient of absorption in water, such that 95% of the laser energy is absorbed in 0.5 mm of water. Thus, the majority of the laser energy is contained superficially, imparting the holmium laser with excellent cutting and tissue ablation properties. It provides sharp incision with simultaneous hemostasis. Perhaps the most significant benefit of the holmium laser is its versatility when delivered through rigid or flexible endoscopes using quartz fibers of various sizes. We present the use of this laser in the ablation of an intravesical ureterocele with calculus.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
2/4. Orthotopic ureterocele masquerading as a bladder tumor in a woman with pelvic pain.Single system orthotopic ureteroceles often present in adulthood are associated with characteristic radiographic findings. We present the case of a 54 year old woman with 8 months of urgency/frequency and pelvic pain that has the cystoscopic appearance of a bladder tumor. Cystoscopic images, radiographs and intraoperative photos demonstrate the work-up, evaluation, and treatment of this unique single system orthotopic ureterocele containing a calculus. This patient demonstrates the need for cystoscopy accompanied by upper tract imaging in patients with new onset pelvic pain, urgency/frequency, and frequent urinary tract infections.- - - - - - - - - - ranking = 0.2keywords = calculus (Clic here for more details about this article) |
3/4. Giant obstructing calculus in the distal ureter secondary to obstruction by a ureterocele.A 43-year-old man presented with bilateral simple ureteroceles complicated by calculi. A huge left ureteral calculus subsequently developed, causing nonfunctioning of the left kidney. This is apparently the largest calculus associated with an orthotopic ureterocele ever reported in the literature. Its cause, diagnosis, and treatment are discussed.- - - - - - - - - - ranking = 1.2keywords = calculus (Clic here for more details about this article) |
4/4. Radiolucent ureterocele calculus. Case report.In a 30-year-old man a radiolucent stone in an orthoptic, nonobstructing ureterocele was detected by ultrasonography of the bladder. The stone was impacted in the ureteral orifice. Endoscopic ureteral meatotomy was performed in preference to endoscopic incision of the ureterocele, and the stone was disintegrated at ureterorenoscopy via the enlarged orifice.- - - - - - - - - - ranking = 0.8keywords = calculus (Clic here for more details about this article) |
