Radiation exposure of patient and surgeon in minimally invasive kidney stone surgery.

Radiation exposure of patient and surgeon in minimally invasive kidney stone surgery. Prog Urol. 2016 May 10; Authors: Demirci A, Raif Karabacak O, Yalçınkaya F, Yiğitbaşı O, Aktaş C Abstract OBJECTIVE: Percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS) are the standard treatments used in the endoscopic treatment of kidney stones depending on the location and the size of the stone. The purpose of the study was to show the radiation exposure difference between the minimally invasive techniques by synchronously measuring the amount of radiation the patients and the surgeon received in each session, which makes our study unique. MATERIALS AND METHODS: This is a prospective study which included 20 patients who underwent PNL, and 45 patients who underwent RIRS in our clinic between June 2014 and October 2014. The surgeries were assessed by dividing them into three steps: step 1: the access sheath or ureter catheter placement, step 2: lithotripsy and collection of fragments, and step 3: DJ catheter or re-entry tube insertion. RESULTS: For the PNL and RIRS groups, mean stone sizes were 30mm (range 16-60), and 12mm (range 7-35); mean fluoroscopy times were 337s (range 200-679), and 37s (range 7-351); and total radiation exposures were 142mBq (44.7 to 221), and 4.4mBq (0.2 to 30) respectively. Fluoroscopy times and radiation exposures at each step were found to be higher in the PNL group compared to the RIRS g...

Authors: Segalen T, Lebdai S, Panayotopoulos P, Culty T, Brassart E, Riou J, Azzouzi AR, Bigot P Abstract OBJECTIVES: During ureteroscopy for urolithiasis, postoperative ureteral drainage with double J stent is frequently used. It may reduce acute postoperative pain and late ureteral stenosis. Double J stent can have negative impact on life quality. After uncomplicated intervention, double J stent is not mandatory. Objective of our study was to evaluate pain and complications after ureteroscopy with or without stent. METHODS: We retrospectively analyzed ureteroscopy performed between May 2014 and January 2017. ...

ConclusionsEnterocystoplasty remains the gold standard for AC, though more research is needed to better evaluate the morbidity of different surgical techniques and the indications for concomitant surgeries. Experimental methods of AC with tissue engineering are a promising area for further investigation.

AbstractTo perform a systematic review and meta-analysis for the evaluation of 22 drug interventions in the management of ureteral stones, MEDLINE, Web of Science, EMBASE, and Cochrane central databases were searched to identify RCTs focusing on the evaluation of the efficacy of multiple drug interventions in medical expulsive therapy (MET) for ureteral stones, with no restrictions on year or language. Study quality assessment and data extraction were performed by independent reviewers. Major outcome measures were the stone expulsion rate, stone expulsion time, and pain episodes during treatment. A total of 78 RCTs with 14...

lkmer B Abstract The increase of medical knowledge and technical innovations together with the demographic change represent a challenge for the new conception of guidelines and clinical studies. The present S2k guidelines, which are exclusively concerned with kidney and ureteral stones, should support the treatment of urolithiasis in hospitals and private practices and provide information on urolithiasis for patients. Increasing interdisciplinary collaboration in stone treatment is also demonstrated in the number of professional and working groups participating in the update of the new guidelines. The present S2k ...

CONCLUSION: The use of fluoroscopy does not alter the complication frequency and stone-free rate. We think that the use of fluoroscopy is not mandatory in cases in which renal pelvis access is achieved especially with semirigid ureteroscopy and that unnecessary fluoroscopy increases radiation exposure.

We report a 54-year-old man who presented with a 1-month history of an enlarged skin mass on the right flank. Diagnoses: The patient was subsequently diagnosed with metastatic SCC involving the patient's integumentary system near the flank region proximal to the right kidney following percutaneous nephrostomy. Interventions: The skin mass and the surrounding muscle tissue of the right flank were excised with a wide resection margin including radial nephrectomy. The soft tissue defect after resection was reconstructed using a unilateral gluteus maximus myocutaneous V-Y advancement flap. Outcomes: No recurrence of t...

AbstractOur objectives were to compare measurements of ureteral wall area, ureteral wall volume and ureteral wall thickness for their use in prediction of shock wave lithotripsy outcomes. We retrospectively identified 218 patients that underwent shock wave lithotripsy for ureteral calculi with pretreatment non-contrast computed tomography. We measured ureteral wall thickness, ureteral wall area and ureteral wall volume by high functional viewer. Ureteral wall thickness was defined as the maximum thickness of ureteral wall, and ureteral wall area as the area of ureteral wall around the stone in the maximal stone diameter on...

Renal colic is a common complaint that presents to the emergency department. It is estimated that 13% of men and 7% of women will develop a renal stone. There is a high probability of recurrence, with 50% within 5  years. Computed tomographic scan of the abdomen and pelvis without contrast and the ultrasound of the kidneys, ureters, and bladder are the common diagnostic imaging modalities used for diagnosis. Initial treatment includes analgesics and medical expulsive therapy. Most of the patients will pass t heir stone spontaneously within 3 days. The remaining 20% will require urologic intervention.
