Complementary Ureterorenoscopy after extracorporeal Shock Wave Lithotripsy in proximal ureteral stones: success and complications

SUMMARY OBJECTIVE: The aim of this study was to demonstrate the effect of extracorporeal shock wave lithotripsy application on the success and complications of ureteroscopic lithotripsy in proximal ureter stones. METHODS: The data of 87 patients who did not respond to shock wave lithotripsy and underwent ureteroscopic lithotripsy were retrospectively analyzed and classified as group I, and 99 patients who received ureteroscopic lithotripsy as primary treatment were classified as group II. Demographic features, response to treatment, and preoperative and postoperative complications were compared between the two groups. RESULTS: There was no difference between the two groups in terms of gender, operation times, stone sizes, and ureteroscope diameters. (p>0.05). Infective complications such as postoperative fever, pyelonephritis, and urosepsis were similar in both groups (p=0.142, p=0.291, and p=0.948). Stone migration was observed in 10 (11.5%) and 6 (6.1%) patients in groups I and II, respectively (p=0.291). Impacted stone was seen in 47 (54%) patients in group I and in 15 (15.2%) patients in group II (p<0.0001). Mucosal laceration occurred in 11 (12.6%) and 3 (3%) patients in groups I and II, respectively (p=0.028). Ureteral perforation was detected in 3 (3.4%) patients in group I and 1 (1%) patient in group II, whereas ureteral avulsion was not observed in either group (p=0.524). CONCLUSIONS: It was concluded that the application of shock wave lithotripsy before ureteroscopic lithotripsy in proximal ureter stones did not affect the success. Although the results are similar in terms of postoperative infection, shock wave lithotripsy application has been found to increase the risk of stone impaction into the mucosa and ureteral laceration.

Extensive Gastric Mucosal Laceration During Endoscopic Examination / 대한소화기내시경학회지

Gastric mucosal lacerations occurring during the course of upper gastroduodenal endoscopy are apparently rare. The location and extent of the lesion are little different from the usual one found in the Mallory-Weiss tear. But the pathogenesis of the gastric mucosal tear is similar to that of Mallory-Weiss tear. Hiatal hernia, atrophic gastritis, and old age are predisposing factors for Mallory-Weiss tear. There is currently only one report about extensive gastric mucosal laceration during performance of endoscopy in an elderly patient. During a standard diagnostic endoscopic procedure, we experienced extensive gastric mucosal laceration that ranged from the gastroesophageal junction to the gastric angle in an elderly woman Furthermore, her body surface area and stomach size were very small. The patient was treated successfully with hemoclip application for the laceration. We report on the case along with a review of the relevant literature.

Gastric mucosal laceration: a complication of manual bag-valve-mask ventilation.

A 73-year-old woman was admitted to our hospital because of severe myocardial infarction. After intratracheal intubation, cardiac catheterization was performed. Thereafter, a nasogastric tube was also inserted to reduce marked gastric distension. Immediately, massive fresh blood was observed from the nasogastric tube, and her blood pressure rapidly went down. Emergent upper gastrointestinal endoscopy demonstrated a bleeding mucosal laceration along the lesser curvature of the stomach, and the laceration was treated endoscopically. Previous autopsy series suggest that gastric lacerations may occur in 2-12% of cases that receive cardiopulmonary resuscitation, but there have been no reports observed and treated endoscopically. Attention to the technique of ventilation may help to minimize the incidence of gastric mucosal lacerations during the peri-resuscitation period. Because hemorrhage from gastric mucosal lacerations may be a source of secondary morbidity or even mortality, evidence of upper gastrointestinal bleeding peri-intubation should be approached aggressively.
