“…Therefore, we could not conclude that preoperative stenting increased postoperative fever rate, although an extended time of stenting may cause potential UTI (Shigemura et al, 2012). Also, the incidence of fever in our patients without preoperative stenting was similar with the results (3.6% for 10–20 mm renal stones) of CROES URS Global Study (Skolarikos et al, 2015). …”

“…Multivariate assessment also revealed that preoperative stent was not the independent predictor of stone-free rate after fURS in our study which was similar with a previous study (Ito et al, 2015). In our opinion, once the fURS successfully arrived at renal pelvis, stone-free rate for renal calculi would be more likely affected by stone characteristics and pelvicalyceal anatomy rather than the existence of preoperative stenting according to our experience and some published data (Skolarikos et al, 2015; Jessen et al, 2014; Resorlu et al, 2012). …”

PurposeTo clarify the outcome of flexible ureteroscopy (fURS) for management of renal calculi without preoperative stenting.MethodsA total of 171 patients who received 176 fURS procedures for unilateral renal stones were reviewed. All procedures were divided into two groups depending on whether they received ureteral stenting preoperatively. Baseline characteristics of patients, stone burden, operation time, stone-free rates, and complications were compared between both groups.ResultsSuccessful primary access to the renal pelvis was achieved in 104 of 114 (91.2%) patients without preoperative stenting, while all procedures with preoperative stenting (n = 62) were successfully performed. A total of 156 procedures were included for further data analysis (56 procedures in stenting group and 100 in non-stenting group). No significant differences was found regardless of a preoperative stent placement in terms of stone-free rate (73.2% with stenting vs. 71.0% without, P = 0.854), operative time (70.4 ± 32.8 with stenting vs. 70.2 ± 32.1 without, P = 0.969).ConclusionsfURS for management of renal stone without preoperative ureteral stenting are associated with well outcome in short term follow-up. Our study may help patients and doctors to decide if an optional stent is placed or not.

“…Which is a preferable treatment method for preserving functioning renal parenchyma [2], and this is crucial to the management of patients with solitary kidney [1]. Unfortunately, RIRS cannot be recommended as first-line treatment due to which stone-free rate (SFR) showed a negative correlation with stone size [7]. SFR after RIRS was achieved in 30% of patients with >2 cm stones and usually needed re-treatment; however, overall complication rates not related to stone sizes [7].…”

Percutaneous nephrolithotomy versus retrograde intrarenal surgery for the treatment of kidney stones up to 2 cm in patients with solitary kidney: a single centre experience

et al. 2017

BackgroundTo compare the treatment outcomes between percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) for the management of stones larger than 2 cm in patients with solitary kidney.MethodsOne hundred sixteen patients with a solitary kidney who underwent RIRS (n = 56) or PCNL (n = 60) for large renal stones (>2 cm) between Jan 2010 and Nov 2015 have been considered. The patients’ characteristics, stone characteristics, operative time, incidence of complications, hospital stay, and stone-free rates (SFR) have been evaluated.ResultsSFRs after one session were 19.6% and 35.7% for RIRS and PCNL respectively (p = 0.047), but the SFR at 3 months follow-up comparable in both groups (82.1% vs. 88.3%, p = 0.346). The calculated mean operative time for RIRS was longer (p < 0.001), but the mean postoperatively hospital stay was statistically significantly shorter (p < 0.001) and average drop in hemoglobin level was less (p = 0.040). PCNL showed a higher complication rate, although this difference was not statistically significant.ConclusionsSatisfactory stone clearance can be achieved with multi-session RIRS in the treatment of renal stones larger than 2 cm in patients with solitary kidney. RIRS can be considered as an alternative to PCNL in selected cases.

“…Daarnaast zijn in de live-URS-groep relatief gezien meer nierstenen verwijderd dan in de routine-URS-groep. Literatuur laat zien dat het aantal complicaties over het algemeen hoger is bij URS voor nierstenen dan bij URS voor ureterstenen [11,12]. In de live-URS-groep waren bovendien meer patiënten met renale anomalieën ingedeeld dan in de routine-URS-groep.…”

SamenvattingDeze retrospectieve studie vergelijkt de behandeluitkomsten voor urinewegstenen van live endo-urologische procedures (live EP) met die van routine endo-urologische procedures (routine EP). Over een periode van vijf jaar werden er 666 ureteroscopische (URS) en 182 percutane (PNL) niersteenbehandelingen verricht, waarvan 151 live EP's. Intraoperatieve complicaties tijdens URS traden op bij 3,2% van de live EP's en 2,5% van de routine EP's (p = 0,72) en postoperative complicaties bij 13,7% van de live EP's en 8,8% van de routine EP's (p = 0,13). Intraoperatieve complicaties tijdens PNL traden op bij 8,9% van de live EP's en bij 5,6% van de routine EP's (p = 0,52) en postoperatieve complicaties bij 28,6% van de live EP's en bij 34,9% van de routine EP's (p = 0,40). Binnen de URS-en de PNL-groepen was er geen significant verschil in Clavien-Dindo-complicatiegraden. Multipele regressieanalyse toonde geen associatie tussen live EP en minder gunstige behandeluitkomsten. Live EP's, zoals uitgevoerd in deze setting, lijken behandeluitkomsten niet te benadelen wanneer deze worden vergeleken met routine EP's.Trefwoorden stenen -urolithiasis · live chirurgie · ureterorenoscopie · percutane nefrolithotomie Outcome from five-year live endourological urinary stone treatment Are outcomes compromised?Abstract This retrospective study compares treatment outcomes for urinary stones of live surgical procedures (LSP) and routine surgical procedures (RSP). Over a five-year period, 666 ureteroscopic (URS) and 182 percutaneous (PNL) procedures were performed, of which 151 LSP's. Among the URS-groups, the intra-and postoperative complication rates were 3.2% for LSP and 2.5% for RSP (p = 0.72), respectively 13.7% for LSP and 8.8% for RSP (p = 0.13). Among the PNL-groups, the intra-and postoperative complication rate were 8.9% for LSP and 5.6% for RSP (p = 0.52), respectively 28.6% for LSP and 34.9% for RSP (p = 0.40). There were no statistically significant differences in Clavien-Dindo complication grades within the URS-and PNL-groups. Multiple regression analyses revealed no association between LSP and less favorable outcomes as compared to RSP. Live surgical endourological demonstrations, as performed in this setting, do not seem to compromise outcomes. IntroductieLive chirurgie is een populair educatiemiddel.
