Stone Recurence After Stone Free Status With Extracorporeal Shock Wave Lithotripsy

Abstract

This results suggested that the stone number, stone history and urological complication were highly related to ipsilateral stone recurrence after stone free status by ESWL. Extracorporeal shock was lithotripsy had probability of higher stone recurrence rate.

Prognostic Factors Effecting on Recurrence of Urinary Stone Disease: A Multivariate Analysis of Everyday Patient Parameters

“…These results were found to be similar with many studies previously done, but not with the others [4,5,15]. For current study and generally, it is reasonable that stone burden might influence probability of remaining residual fragments, or might be a reflection of etiologic factors such as urinary tract infection or metabolic abnormalities causing higher recurrence rate.…”

“…Iguchi et al [12], in their experimental study, discovered that female sex hormones could inhibit renal crystal deposition in rats. However there are also studies claiming ineffectiveness of sex on stone recurrence like our study [3,5,10,13]. In addition the fact that the male to female ratio was almost equal in our study might reflect the higher incidence of infection stones in females.…”

“…So, it has been investigated on many risk factors to define recurrence potential of the patient with urinary stone up to now, but it has not been exactly obtained any consensus on prognostic factors influencing stone recurrence risk [1]. For instance; whether a number of factors such as gender or stone burden affect on stone prognosis has not been unequivocally revealed [3,4,5]. In other words further studies exposing stone prognosis have been still needed.…”

465 Does lithotripsy increase stone recurrence? A comparative study between extracorporeal shock wave lithotripsy and non-fragmenting percutaneous nephrolithotomy

“…In our present study, the recurrence rates at 1, 5 and 10 years after ESWL were 0.8%, 35.8% and 60.1% using KaplanMeier analyses. Other studies have also calculated cumulative recurrence rates using the Kaplan-Meier method [17,18]. In one study [17], the overall ipsilateral recurrence rates were 3.5%, 21.2%, 34.7% after 1, 3 and 5 years, respectively; and the contralateral stone recurrence rates were 1.9%, 7.5%, 12.8%, respectively.…”

Course of Calcium Stone Disease without Treatment. What Can We Expect?

“…During the recent 5 years a series of studies [29, 30, 31, 32]reported recurrences after ESWL. Recurrence rates and stone frequencies are given in table 5c.…”
