Introduction. To evaluate the efficacy of combined endoscopic lithotomy and extracorporeal shock wave lithotripsy (ESWL), and additional electrohydraulic lithotripsy (EHL) as needed, for the treatment of pancreatic duct stones, we retrospectively evaluated 98 patients with chronic pancreatitis and pancreatic lithiasis.Methods. For the management of main pancreatic duct (MPD) stones in 98 patients, we performed combined endoscopic treatment (ET)/ESWL therapy as the first treatment option. When combined ET/ESWL was unsuccessful, EHL with the SpyGlass Direct Visualization system or X-ray guided EHL was performed. Outpatient ESWL was reserved as one of the final treatment options.Results. Fragmentation was successful in 80 (81.6%) patients as follows: combined ET/ESWL: 67 cases; SpyGlass EHL: 4 cases; X-ray guided EHL: 3 cases; and outpatient ESWL: 6 cases. Successful outcome was obtained by combined ET/ESWL in 67 of the 98 patients (74.5%), by EHL in 7 of 14 patients (7.1%), and by outpatient ESWL in 6 of 6 patients (6.1%). Negotiating the guidewire through a severe MPD stricture was significantly associated with a higher rate of stone fragmentation (P=0.0003).Conclusions. In cases where combined ET/ESWL was not successful for stone clearance, EHL using the SpyGlass system or X-ray guided EHL was effective in cases where the guidewire could be negotiated through the MPD stricture and it increased the fragmentation rate.

AbstractBackground and ObjectiveExtracorporeal shock wave lithotripsy (ESWL) for common bile duct (CBD) stones has been used in the past, but experience is limited. We report our experience of ESWL in the management of difficult CBD stones.MethodsPatients with difficult-to-retrieve CBD stones were enrolled and underwent ESWL. Fluoroscopy is used to target the stones after injection of contrast via nasobiliary drain. CBD clearance was the main outcome of the study.ResultsEighty-three patients were included (mean age 50.5 ± 14.5 years); these patients were mainly females (43; 51.8%). Large stones >15 mm were noted in 64 (77.1%), CBD stricture in 22 (26.5%) and incarcerated stone in 8 (9.6%) patients. Patients needed 2.1 ± 1.2 sessions of lithotripsy and 4266 ± 1881 shock waves per session. In 75 (90.3%) patients, the fragments were extracted endoscopically after ESWL, while spontaneous passage was observed in 8 (9.6%). Total CBD clearance was achieved in 67 (80.6%) patients, partial clearance in 5 (6%) and no response in 11 (13.2%). Failure of the treatment was observed in large stone with size ≥2 cm (P = 0.021), incarcerated stone (P = 0.020) and pre–endoscopic retrograde cholangiopancreatography cholangitis (P = 0.047).ConclusionESWL is a noninvasive, safe and effective therapeutic alternative to electrohydraulic lithotripsy and surgical exploration for difficult biliary stones.

Edmundas Štarolis, Laimutis Andreika, Egidijus Gatelis, Valdemaras Dasevičius, Darius ŠilinisVilniaus miesto universitetinės ligoninės Urologijos skyrius,Antakalnio g. 57 LT-10207 VilniusEl paštas: [email protected] Įvadas / tikslas Ekstrakorporinė smūginės bangos litotripsija dažniausia yra pirmo pasirinkimo būdas gydant šlapimtakių akmenligę. Mes įvertinome akmenų dilimo ir išsivalymo rezultatus, atsižvelgdami į akmenų padėtį, dydį, hidronefrozės laipsnį, akmens įstrigimo šlapimtakyje laiką, inkstų dieglių skausmus. Ligoniai ir metodai Atlikus retrospektyvųjį tyrimą, įvertinti 362 ligonių 371 šlapimtakių akmens šalinimo rezultatai. Nuo 2003 m. sausio 1 d. iki 2004 m. gruodžio 31 d. atliktos 702 gydymo procedūros. Akmenų padėtis ir dydis buvo įvertinami apžvalginės urogramos ar intraveninių urogramų būdu, inkstų diegliai ir akmenų įstrigimo laikas – iš anamnezės ir klinikinių duomenų, hidronefrozės laipsnis – atliekant ultragarsinį inkstų tyrimą ir intravenines urogramas. Skilimo rezultatas įvertintas išrašant ligonį iš stacionaro, likusių fragmentų pasišalinimas – po 3 mėnesių rentgenografijos būdu. Gydymas buvo neveiksmingas, jei rasti likę 4 mm ar didesni fragmentai. Rezultatai Šlapimtakių viršutinio ir apatinio trečdalio akmenys statistiškai reikšmingai geriau fragmentuojasi ir išsivalo negu vidurinio trečdalio. Lyginant viršutinio ir apatinio trečdalio akmenų šalinimo rezultatus, skirtumo nerasta. Inkstų diegliai neturėjo įtakos nei fragmentacijos, nei išsivalymo rezultatams. Hidronefrozės laipsnis turėjo įtakos skilimo rezultatams (didesnio hidronefrozės laipsnio naudai), bet lyginant pagal šį požymį išsivalymo rezultatus, statistiškai reikšmingo skirtumo nepastebėta. Pagal gydymo baigties priklausomybę nuo akmens įstrigimo šlapimtakyje laiko, fragmentacijos rezultatai nesiskyrė, bet išsivalymas statistiškai reikšmingai geresnis, jei akmuo įstrigęs mažiau nei prieš 1 mėn. Dažniausia rezultatai skyrėsi grupių, suskirstytų pagal akmenų dydį: gauta atvirkštinė gydymo rezultatų priklausomybė tiek fragmentacijos, tiek išsivalymo atžvilgiu. Išvados Geriausi gydymo rezultatai gauti šalinant šlapimtakių viršutinio ir apatinio trečdalio nedidelius (iki 7 mm), neseniai (iki 1 mėn.) įstrigusius akmenis. Inkstų diegliai neturėjo įtakos gydymo rezultatams. Reikšminiai žodžiai: ekstrakorporinė smūginės bangos litotripsija, šlapimtakių akmenligė, gydymas Efficacy of extracorporeal shock wave lithotripsy treatment of ureteral stones Edmundas Štarolis, Laimutis Andreika, Egidijus Gatelis, Valdemaras Dasevičius, Darius ŠilinisVilnius City University Hospital, Department of Urology,Antakalnio g. 57 LT-10207 Vilnius, LithuaniaE-mail: [email protected] Background / objective Extracorporeal shock wave lithotripsy is considered as a first line treatment for the majority of ureteral stones. We investigated fragmentation and stone-free rates, depending of their localization, presence of renal colic, degree of hydronephrosis, the impact time and size of the stones. Patients and methods There is a retrospective study evaluating treatment of 371 ureteral stones for 362 patients in our department since January 1, 2003 to December 31, 2004. A total of 702 treatment sessions have been performed. Localization and size of the stones were evaluated by plain X-ray and / or intravenous pyelography. Presence or absence of renal colic, the time of impact were evaluated by anamnesis and clinical features and the degree of hydronephrosis by ultrasound and / or intravenous pyelography. The fragmentation rate has been evaluated before discharging and stone-free rate 3 months later by X-ray. Treatment failure has been considered, if 4 mm or larger fragments were still present. Results Stones in the upper and lower ureter, comparing with those in the middle, had a statistically significantly better fragmentation and stone-free rates. There was no significant difference in the treatment results between the upper and lower ureter stones. Presence or absence of renal colic did not correlate with fragmentation nor stone-free rates. The degree of hydronephrosis correlated with fragmentation rate in favour of a higher dilatation group, but not with a stone-free rate. Fragmentation rate did not correlate with the time of impact, but a correlation has been found comparing these two groups by stone-free rate, in favour of the shorter time of impact. The correlation was best comparing the groups according to the size of stones. The smaler stone-size groups demonstrated a statistically significantly better fragmentation as well as higher stone-free rates. Conclusions We found extracorporeal shock wave lithotripsy treatment most effective for treating the upper and lower ureter, smaller size (< 7 mm), shorter time of impact (less than 1 month) stones. Presence or absence of renal colic did not correlate with fragmentation nor stone-free rates. Keywords: extracorporeal shockwave lithotripsy, ureteral calculi, treatment

Aim: To evaluate the clinical efficiency of computed tomography for diagnostics of patients with urolithiasis and the choice of treatment strategy. Material and methods: The study was carried out at the Urological Clinic of I.M. Sechenov First Moscow State Medical University and included 1044 patients with urinary stones. The ultimate goal of this study was to predict the clinical efficiency of extracorporeal shock wave lithotripsy using a combination of computed tomography and densitometry. Extracorporeal shock wave lithotripsy was performed on “Siemens Lithostar Plus,” “Siemens Modularis Uro,” and “Dornier Gemini” lithotripters. Statistical analysis of clinical data included evaluation of individual sampling groups and calculation of weighted arithmetic mean ( M). Results: The efficiency of extracorporeal shock wave lithotripsy has been determined primarily using X-ray analysis of the concrement outlines and the structure (homogeneous or heterogeneous) of its central zone. However, in terms of efficiency and repetition rate (the number of fragmentation procedures required for complete clearance) of extracorporeal shock wave lithotripsy, the mean density of the concrement along the whole length of its three-dimensional structure (expressed in Hounsfield units) appeared to be the most reliable and informative predictive index in this study. Conclusion: The combination of computed tomography with densitometry in the treatment of patients with urolithiasis allows one (1) to determine the exact localization, size, X-ray structure, and structural density of urinary stones and (2) to predict, on the basis of densitometric data histograms, the clinical efficiency and repetition rate of extracorporeal shock wave lithotripsy with due regard to the X-ray structure of peripheral and central zones, and mean density (in Hounsfield units) of urinary concrements.
