The Impact

Introduction: Our study explored the impact of switching from surgeon- to radiation technologist (RT)-controlled fluoroscopy on fluoroscopy and operative times. We also identified factors impacting fluoroscopy and operative times for ureteroscopy (URS) with laser lithotripsy.Methods: Patients undergoing urological procedures requiring fluoroscopy six months before and after the change from surgeonto RT-controlled fluoroscopy were identified. Median fluoroscopy and operative times were compared between cohorts. Subgroup analyses were performed based on procedure performed. A multivariate analysis identified factors associated with increased fluoroscopy and operative times for URS with laser lithotripsy.Results: Overall, no difference was found between surgeon and RT cohorts for fluoroscopy (58.0 vs. 56.7 seconds; p=0.34) or operative times (39 vs. 36 minutes; p=0.14). For URS with laserlithotripsy, fluoroscopy and operative times were longer in the surgeon-controlled cohort (76.0 vs. 54.0 seconds; p<0.01 and 48 vs. 40 minutes; p<0.01, respectively). For URS only, fluoroscopy time was decreased in the surgeon-controlled cohort (47.0 vs. 73.0 seconds; p=0.01). For URS with laser lithotripsy, factors independently associated with increased fluoroscopy time were male sex, flexible URS, glidewire use, and difficult ureteric stent insertion (p<0.05). Flexible ureteroscopy, glidewire use, previous ureteric stent placement, and difficult ureteric stent insertion were independently associated with increased operative time (p<0.05).Conclusions: Fluoroscopy and operative times are not significantly influenced by who controls fluoroscopy during urologic procedures. Patients undergoing URS with laser lithotripsy have decreasedfluoroscopy and operative times with RT-controlled fluoroscopy. Patients undergoing URS only have decreased fluoroscopy times with surgeon-controlled fluoroscopy.

This case exemplifies an unusual anatomical variation of a common presentation and highlights the importance of perioperative diagnosis and planning in complex surgical patients. A 72-year-old comorbid man presented to the emergency department with an infected obstructed right kidney secondary to an obstructing 12 mm vesicoureteric junction calculi. However, imaging also showed concurrent ureteroinguinal hernia associated with a 130 cm-long ureter, too long for conventional treatment with a ureteric stent. Acutely, the patient’s collecting system was decompressed via nephrostomy, but due to the rarity of this anatomical variation, definitive treatment had to be rethought to help reduce the risk of iatrogenic damage and the associated long-term complications.

AbstractEndoscopic retrograde cholangiopancreatography (ERCP) is the current treatment of choice in bile duct stones. Several factors such as variant anatomy of ampulla and surgical procedures like hepaticojejunostomy limit the success of ERCP in treating bile duct stones. Percutaneous transhepatic laser lithotripsy using interventional radiologic and endourologic techniques, which is uncommon, is a reasonable treatment option in such difficult cases. It is a minimally invasive, safe procedure accompanied by a high success rate, minimal morbidity, and a short hospital stay. We report our technique and experience in a series of three patients who underwent percutaneous transhepatic biliary drainage (PTBD) followed by percutaneous transhepatic laser lithotripsy in an attempt to avoid open surgery when ERCP was technically difficult.

Objectives: Holmium: YAG laser has gained its popularity throughout the years and is used to treat sialolithiasis, which helps to overcome the limitations of traditional sialendoscopic lithotripsy for larger-sized salivary stones. However, little information is available regarding factors predicting the success rate of Holmium: YAG laser intraductal lithotripsy. The purpose of this study is to investigate the factors affecting the success rates of Holmium: YAG laser lithotripsy for salivary stones treatment in a tertiary care hospital. Methods: A retrospective study conducted in patients receiving sialolithiasis surgery under sialendoscopy from May 2013 to March 2015 at Mackay Memorial Hospital, Taiwan. Data on various factors, including patients’ age, gender, glands, size of largest stone, multiple stones (≥2 stones), location of the stone (distal duct, middle duct, proximal duct, and hilum), and operative time. The success of the surgery defined as patients without any complaints such as swelling or tenderness. Logistic regression and Fisher exact tests were employed to examine these factors on the success rate. Results: Fifty-four patients who received sialendoscopy surgery with a mean age of 35.74 years old recruited. Logistic regression identified the operation time exceeding 210 minutes showed 23.497 folds higher odd ratio of having a result of operation failure ( P < .05). Conclusion: The prolonged operation time is the sole independent factor affecting the successful outcome for salivary gland intraductal laser lithotripsy. We recommend operative time be no more than 210 minutes to increase the success rate in salivary gland Holmium: YAG laser intraductal lithotripsy.
