Disease relevance of Ureteroscopy

• MATERIALS AND METHODS: A total of 16 patients with ureteral stenosis underwent surface rendering CT ureteroscopy after the intravenous administration of contrast material and furosemide [1].
• A 45-year-old man with a history of cyclophosphamide exposure underwent repeated ureteroscopy for positive urine cytology findings after resection of a Grade 2 papillary transitional-cell carcinoma of the bladder [2].
• CONCLUSIONS: Ureteroscopy and holmium laser lithotripsy can be performed safely in all stages of pregnancy, providing definitive management of symptomatic ureteral calculi [3].

High impact information on Ureteroscopy

• At the same time Marshall contributed to the development of ureteroscopy for stone disease [4].
• PURPOSE: Loss of active deflection with insertion of a holmium laser fiber can significantly decrease the efficacy of intrarenal flexible ureteroscopy [5].
• MATERIALS AND METHODS: A total of 54 flexible ureteroscopy procedures were randomized to use of the 12/15Fr Applied Access Forte XE (Applied Medical, Rancho Santa Margarita, California) or the 12/14Fr Cook Flexor (Cook Urological, Spencer, Indiana) access sheaths [6].
• RESULTS: A total of 18 patients with uric acid calculi were treated with holmium:YAG lithotripsy by ureteroscopy (5), retrograde nephroscopy (2), percutaneous nephrolithotomy (5) or cystolithotripsy (6) [7].
• During the last 2 years we have been able to perform repeatedly office-based flexible surveillance ureteroscopy without fluoroscopy and without oral or parenteral analgesics in both patients [8].

Anatomical context of Ureteroscopy

• In 15 patients ureteroscopy (URS) was performed with lignocaine jelly in the urethra only, and in 118 with additional intravenous analgesia [9].

Associations of Ureteroscopy with chemical compounds

• During ureteroscopy and intracorporeal lithotripsy every effort should be made to prevent calcium oxalate particles from becoming embedded in the ureteral wall [10].
• PATIENTS AND METHODS: We treated 19 consecutive patients having proximal-ureteral stones using semirigid ureteroscopy, a Stone Cone Nitinol urologic retrieval coil, and holmium:YAG laser lithotripsy with a 200- or 365-microm fiber [11].
• PATIENTS AND METHODS: Between October 2000 and May 2002, 340 ureteroscopies were performed for the treatment of ureteral stones in the Rabin Medical Center. Of this series, 9 patients (2.6%) underwent UUL using a semirigid 8F ureteroscope (Wolf) and an Olympus ultrasonic lithotripter (LUS-1) with a 4.5F hollow probe [12].
• Patients undergoing uncomplicated ureteroscopy were randomized to the Bard Inlay, Cook Endo-Sof, Microvasive Contour, Applied Medical Vertex, or Surgitek Classic Double-Pigtail stent [13].
• CONCLUSIONS: Nephron sparing approaches in well-selected patients with low stage and low-grade disease can be treated endoscopically with ureteroscopy and percutaneous renal surgery [14].

Gene context of Ureteroscopy

• To compare the performances of 2 pulsed lasers, the pulsed dye laser (Candela) and solid Q switched laser (HMT), for the treatment of these calculi 161 ureteral stones were treated successively from November 1990 to March 1992 by a combination of ureteroscopy and laser [15].
• The presence of early vesicoureteral reflux after ureteroscopy has not been investigated [16].
• CONCLUSIONS: The combination of ureteroscopy and laparoscopy has made the management of upper tract TCC totally endoscopic, providing decreased morbidity while maintaining cancer control [17].
• RESULTS: Men tolerated SWL better than ureteroscopy [18].

Analytical, diagnostic and therapeutic context of Ureteroscopy

• PURPOSE OF REVIEW: Ureteroscopy has assumed an expanded and important role in the treatment of proximal ureteral and intrarenal calculi with the development of new endoscopes, more effective grasping devices, and the holmium laser lithotriptor [19].
