“…However, it has been reported that during the 10-month follow-up period, two techniques can cause almost equal damage [14]. In another study, it was reported that percutaneous single and multiple access had similar effects on renal function [15]. Although the literature shows the negative effects of obstruction on renal function, there is inadequate data on the functional effects of RIRS and URS procedures.…”

Aim: The aim of this prospective clinical study was to evaluate the preoperative and postoperative intrarenal vascular parameters of the kidneys undergoing URS and RIRS operations and compare the outcomes with the results of the normal contralateral kidneys. Materials and Methods: A total of 89 patients were included in the study. There were 42 and 47 patients in RIRS and URS groups respectively. The ureteral tract with stone formation was named as operated side, and the contralateral side was named as non-operated side. Preoperative gray-scale and CDUS measurements were obtained 24 h before and 8 h after the operations. The RI measurements were calculated from the upper pole, middle area, and the lower pole of the kidney and averaged. Results: There was no statistically significant difference in the demographic and peroperative features between the two groups except for irrigation fluid volume. Preoperative mean RI values were higher than the contralateral non-operated side kidney but not statistically significant (p=0,346). The ∆RI values were higher on the operated side in RIRS group compared with URS according to the selected surgery method (p=0,041). Discussion: Endoscopic stone surgery procedures increase renal vascular resistance by increasing intrarenal pressure. Therefore, we recommend reducing the use of irrigation fluids as much as possible during surgical applications.

“…Bayrak et al [ 21 ] also showed decreased renal function in the early period after PNL, but renal function was not affected by the number of access sites. Even though Demirtas et al [ 22 ] reported preserved renal function as assessed by DMSA after PNL, the study showed significantly decreased differential renal function on the treated side in the early and late postoperative periods and showed insignificant change on the nontreated side in the late postoperative period. In other reports, in which renal function after ESWL and PNL was evaluated with DMSA, there were no significant changes after ESWL but a significant change after PNL [ 23 ].…”

PurposeTo report the outcome of laparoscopic pyelo- and ureterolithotomies with the aid of flexible nephroscopy.Materials and MethodsA retrospective analysis was performed in 71 patients with complex renal stones or large and impacted proximal ureteral stones. Patients underwent laparoscopic pyelo- or ureterolithotomies with or without the removal of small residual stones by use of flexible nephroscopy between July 2005 and July 2010. Operative success was defined as no residual stones in the intravenous pyelogram at 12 weeks postoperatively. Perioperative results and surgical outcomes were analyzed.ResultsThe patients' mean age was 54.7±13.7 years, and 53 males (74.6%) and 18 females (25.4%) were included. The mean maximal stone size was 19.4±9.4 mm. A total of 47 cases were complex renal stones and 24 cases were impacted ureteral stones. Mean operative time was 139.0±63.7 minutes. Stones were completely removed in 61 cases (85.9%), and no further ancillary treatment was needed for clinically insignificant residual fragments in 7 cases (9.9%). For complex renal stones, the complete stone-free rate and clinically significant stone-free rate were 80.9% and 93.6%, respectively. Multivariate analysis showed that the use of flexible nephroscopy for complex renal stones can reduce the risk of residual stones. A major complication occurred in one case, in which open conversion was performed.ConclusionsLaparoscopic stone surgery is a safe and minimally invasive procedure with a high success rate, especially with the aid of flexible nephroscopy, and is not associated with procedure-specific complications.

“…Renal functions may be more stable in the lateterm evaluation because early-term evaluation may be influenced by many postoperative metabolic factors. Demirtas et al revealed that the kidney functions decreased in the very early hours after surgery then recovered in the late-term follow-up [17]. Reeves et al reported that kidney functions for all CKD group patients improve in long term follow-ups; however increase in CKD group II, IIIa and IIIb patients were statistically significant, but others were not [18].…”

Böbrek Taşı Tedavisinde Retrograd Intrarenal Cerrahinin Böbrek Fonksiyonuna Etkisi

et al. 2021

Bu çalışmada, Retrograd İntrarenal Cerrahi sonrasında eGFR'yi analiz ederek böbrek fonksiyonundaki değişikliği değerlendirmeyi ve değişikliği etkileyen faktörleri sunmayı amaçladık. Yöntem: Mayıs 2018 ile Şubat 2019 arasında böbrek taşı nedeniyle RIRS yapılan 88 hastayı prospektif olarak analiz ettik. eGFR, ameliyat öncesi, ameliyat sonrası ilk gün, ameliyat sonrası ilk ay ve ameliyat sonrası üçüncü ayda MDRD formülü ile hesaplandı. Tüm veriler takip formuna kaydedildi. Tüm işlemler genel anestezi altında yapıldı. Bulgular: Çalışmanın taşsızlık oranı %79,5 idi. Preoperatif eGFR 99,86 mL/dak/1.73m 2 idi. eGFR, postoperatif ilk günde 101.80 mL/dak/1,73m 2 ve üçüncü ay takibinde 111,66 mL/dak/1,73m 2 olarak hesaplandı. eGFR'deki değişiklik erken dönemde 1,94 mL/dak/1,73m 2 ve uzun dönem takip döneminde 11,8 mL/dak/1,73m 2 idi. Üçüncü ay takiplerinde preoperatif böbrek fonksiyonuna göre ve erken döneme göre eGFR'de istatistiksel olarak anlamlı bir iyileşme vardı. Sonuç: Eski taş çıkarma yöntemlerinin aksine RIRS, postoperatif böbrek fonksiyonunda stabilizasyon sağlayabilmektedir. Hatta preoperatif böbrek fonksiyonu bozuk olan hastalarda operasyon sonrası böbrek fonksiyonlarında düzelmeye yardımcı olabilmektedir. Ürologlar, ameliyat sonrası böbrek fonksiyonlarında iyileşme olmasını istedikleri hastalarda RIRS seçeneğini akılda tutabilirler.
