Modular flexible ureteroscope combined with holmium laser lithotripsy in treatment of renal Calculi: a report of 60 cases
Journal of Shanxi Medical University, 2013Co-Authors: Ren Ruimi, Ren RuimiAbstract:Objective To evaluate the efficacy of modular flexible ureteroscope combined with holmium laser lithotripsy in treatment of renal Calculi.Methods A total of 60 patients with renal Calculi were treated with modular flexible ureteroscope combined with holmium laser lithotripsy in our hospital from April 2012 to April 2013.There were 35 cases of renal caculi in middle and upper calyx,15 cases in lower calyx,8 cases in renal pelvic,and 2 cases in multiple calyxes.The Calculi diameter ranged from 8 mm to 35 mm,and averaged 16 mm.Results Of 60 cases,59 cases were successful through ureteroscope.Fifty-five cases were treated successfully at one time for caculi clearance.The operation time was 50-160 min(averaged 123 min).No severe complications such as hemorrhea or ureteral perforation occurred.The patients were discharged from hospital in 3-5 d(averaged 4 d) after operation.Conclusion Modular flexible ureteroscope combined with holmium laser lithotripsy is effective and safe in treatment of renal Calculi,especially for patients with minor stones.

Renal Calculi chemical composition in patients with recurrent nephrolithiasis in the Republic of Moldova: an experimental study
Revista de Ştiinţe ale Sănătăţii din Moldova, 2015Co-Authors: Banov Pavel, Ceban EmilAbstract:Catedra de urologie și nefrologie chirurgicală, Universitatea de Stat de Medicină și Farmacie „Nicolae Testemiţanu”, Chișinău, Republica MoldovaIntroducere. Litiaza renală este o maladie polietiologică, care se impune ca o problemă socială și financiară, cauzată de recidivele ei multiple. Impactul maladiei poate fi diminuat prin tratamentul profilactic al pacienţilor cu urolitiază recidivantă. Cunoașterea particularităţilor regionale ale componenţei chimice a Calculilor renali este importantă pentru selectarea tacticii de tratament. Scopul lucrării a fost cercetarea componenţei chimice a Calculilor la pacienţi cu urolitiază recidivantă. Material și metode. Au fost analizaţi 110 Calculi renali prin metoda chimică după Hodgkinson, modificată, și prin spectroscopie în infraroșu, cu transformata Fourier. Rezultate. Cel mai frecvent, au fost determinaţi Calculi din oxalat de calciu; total – 43 (39,1%); whewellite – 27 (24,6%); weddelite – 16 (14,5%), urmaţi, după frecvenţă, de cei compuși din acid uric – 28 (25,5%). Calculi din fosfaţi au fost identificaţi în 23 (20,9%) de cazuri (fosfat de calciu – 9 (8,2%), struvită – 13 (11,8%), brushite – 1 (0,9%) cazuri. În 16 (14,5%) cazuri, au fost depistaţi Calculi de compoziţie mixtă (whewellite + carbonat apatită – 3 (2,7%), whitlockite + proteină – 5 (4,5%), whewellite + acid uric – 4 (3,6%) cazuri). Alte compoziţii s-au întâlnit rar. Concluzii. Calculii renali din oxalat de calciu, acid uric și cei micști, din oxalat de calciu și acid uric, sunt cel mai frecvent întâlniţi în Republica Moldova. Incidenţa relativ înaltă a Calculilor infectaţi (22,7%) argumentează necesitatea tratamentului antibacterian adecvat în perioada pre- și postoperatorie. Datele obţinute ar putea ajuta la ţintirea tratamentului și la o metafilaxie mai eficientă.Introduction. Nephrolithiasis is a polyetiologic disease, seen as a social and financial problem due to multiple recurrences. Impact of the disease can be reduced by prophylactic treatment of patients with recurrent urolithiasis. Knowledge of regional peculiarities of the chemical composition of renal Calculi is important for the treatment strategy selection. Chemical composition of urinary Calculi structure has not yet been studied in the Republic of Moldova. Material and methods. One hundred and ten kidney Calculi were analyzed using chemically modified method by Hodgkinson and infrared spectroscopy with Fourier transformant. Results. The most commonly calcium oxalate Calculi (total – 43 (39.1%); whewellites – 27 (24.6%); weddelites – 16 (14.5%)) were determined, being followed in frequency by uric acid – 28 (25.5%). Calculi phosphates have been identified in 23 (20.9%) cases (calcium phosphate – 9 (8.2%), struvites – 13 (11.8%), the brushitis – 1 (0.9%) patients). In 16 (14.5%) cases Calculi of mixed composition (whewellites + apatite carbonate – 3 (2.7%), whitlockites + protein – 5 (4.5%), whewellites + uric acid – 4 (3.6%) patients) were detected. Other Calculi types were rarely found. Conclusions. Kidney Calculi from calcium oxalate, uric acid and calcium oxalate and uric acid mixed Calculi are the most frequently found in Moldova. Relatively high incidence of infected Calculi (22.7%) justifies the necessity of appropriate antibacterial therapy in the pre- and postoperative period. The obtained data could help at treatment precision and efficient metaphylaxis

Urinary Silicate in Calculous Patients
Urolithiasis 2, 1994Co-Authors: W. C. ThomasAbstract:Silicate Calculi are frequent in herbivorous animals1 and small amounts of silicate are regularly present in human Calculi2. Recently it has been reported that the presence of polymerized silicate will decrease the concentrations of calcium and phosphorus required for mineralization of tissues in vitro 3. Previously the author has reported that the addition of small amounts of polymerized silicate to urine of normal subjects, 5 to 20 mg per 100 mL of urine, will overcome the effect of inhibitors of mineralization in such urine4.

Ureteroscopic Pneumatic Lithotripsy for Residua Ureteral Calculi after Extracorporeal Shockwave Lithotripsy
Medical Recapitulate, 2008Co-Authors: Mai Yin-yinAbstract:Objectiv to evaluate clinical efficacy of ureteroscopic pneumatic lithotripsy for residua ureteral Calculi after ESWL.Methods 85 patients with ureteral calcui that treated with uretterosopic pneumatic lithotripsy after unsuccessful ESWL were analyzed.Results 79 of 82 patients with ureteral Calculi were succeeded pneumatic ureteroscopic lithotripsy at the one time.3 patients with big stone returned to kidney were given ESWL for second time.The Calculi in all patients were discharged thoroughly after two month.Only one case was treated with operation because naarrowed ureter was difficult for ureterospoce to reach the stone.The other two patients was treated with operation because the perforation was occured during the application of ureteroscope because of resulting from the narrow below calculus.Conclusion Ureteroscopic pneumatic lithotripsy is a safe and effective treatment for residua ureteral Calculi after ESWL.It should be considered as the first choice of treatment.
