1/10. 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.

2/10. holmium laser for management of ureterocele calculi.

    BACKGROUND AND OBJECTIVES: Although most ureteral calculi will pass spontaneously, those in a ureterocele will usually not pass beyond the stenotic orifice. We address both the stone and the underlying anatomic abnormality of a ureterocele using the holmium:YAG laser. STUDY DESIGN/MATERIALS AND methods: We report the first use of the holmium laser to treat ureteral calculi and the ureteroceles responsible for their retention. RESULTS: Two patients have been successfully treated using the described procedure. CONCLUSIONS: The flexibility to treat both the underlying anatomic abnormality and the resultant stone with a single minimally invasive device makes the holmium laser ideal in this situation.

3/10. Giant stone in a complete duplex ureter with ureterocele. A case report.

    We describe a case of a monolateral duplex system and a ureterocele containing a gigantic stone in a 65-year-old woman who presented with pyelonephritis without any previous history of urinary tract infections or stone disease. Stone removal and double left ureteroneocystostomy with plastic widening of a narrowed obstructive side were performed. The ureteral stone measured 10.5 cm in greatest diameter, weighed 85 g and contained calcium oxalates and phosphates. Three months after surgery, radiology (intravenous urography and cystography) showed left unobstructed upper and lower urinary tracts and the absence of vesicoureteral reflux. urine culture was negative 3, 6 and 9 months after surgery.

4/10. Endoscopic management of milk of calcium-filled ureterocele stump.

    A 38-year-old woman with a duplicated right collecting system and a history of right upper-pole heminephrectomy was referred for persistent dysuria and right lower-quadrant abdominal discomfort. Imaging identified a remnant ureter and a ureterocele filled with what appeared to be a large homogenous stone. At cystoscopy, the ureterocele was incised with a holmium:YAG laser, releasing a large quantity of white milky fluid (milk of calcium). There was no evidence of any solid material. Endoscopic evaluation should be the first step in patients with stones in a ureteral stump because milk of calcium may be the etiology of what appears to be a large stone burden in an obstructed system.

5/10. Radiolucent seed calculi in an orthotopic ureterocele.

    We report a case of radiolucent seed calculi in an orthotopic ureterocele. The diagnosis was based on clinical suspicion and confirmed by ultrasonography.

6/10. 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.

7/10. Stones in orthotopic, non-obstructing ureteroceles.

    A case is presented in which stones were found bilaterally in orthotopic, non-obstructing ureteroceles in a child. This is apparently the first reported instance of this condition occurring in the presence of sterile urine. A review of related literature gives clues to the possible etiology of such an occurrence.

8/10. Seed calculi an ectopic ureterocele: a case report.

    We report a case in which the gravitational properties of seed calculi were demonstrated on plain films and excretory urography in an ectopic ureterocele. Upright and supine films are of importance to preclude other etiologies for abdominal calcification.

9/10. Bilateral intravesical duplex system ureteroceles with multiple calculi in an adult patient.

    We present a case report of an adult female patient with bilateral duplex system ureteroceles, containing multiple small stones. There was no history of urinary tract infections or stone disease. Treatment consisted of right upper pole heminephrectomy because of non-function and transurethral incision of the left ureterocele, resulting in almost complete removal of the calculi. Furthermore no vesicoureteral reflux was seen 3 months postoperatively. Transurethral incision is a safe and effective treatment in removing stones in ureteroceles without necessitating further treatment because of vesicoureteral reflux.

10/10. 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.
