    The relationship between the severity of pain and stone size, hydronephrosis and laboratory parameters in renal colic attack
    (W.B. Saunders, 2019) Sasmaz M.İ.; Kirpat V.
    Objective: In this study, we investigated the relationship between the severity of pain level and hydronephrosis, hematuria and pyuria presence in the acute renal colic attack and whether there was a correlation between the stone size and inflammatory markers. Methods: The patients' pain scores determined by Visual Analog Scale (VAS), CRP, WBC and NLR levels from the laboratory results, hematuria and pyuria presence in the urine analysis and hydronephrosis presence in the imaging methods were recorded. Moreover, stone size was measured for the patients for whom computed tomography (CT) method was applied. Results: Mean age of the 275 patients was 41.0 ± 14.9 and 61.1% of them were male. The patients' mean VAS score was 73.3 ± 16.5.The mean VAS score of the groups of which hematuria and pyuria were positive and which have hydronephrosis finding was statistically higher than those whose were negative. The mean stone size was 5.2 ± 2.1 mm, and those with signs of hydronephrosis on their CT (n = 66) were 5.4 ± 2.3 mm, while those with no signs of hydronephrosis (n = 57) were 4.9 ± 1.7. No statistical difference was found in stone size between patients with hydronephrosis and those without. Not any correlations were determined between the stone size and VAS pain score of the cases. Conclusions: We detected that the pain level was not correlated with the stone size and big stones were not statistically riskier in the hydronephrosis development. However, we think that the risk of complications such as hydronephrosis is higher in the patients whose pain level are higher and the infection may be accompanied by this group. © 2019 Elsevier Inc.

    Comparison stone-free rate and effects on quality of life of percutaneous nephrolithotomy and retrograde intrarenal surgery for treatment of renal pelvis stone (2-4cm): A prospective controlled study
    (Lippincott Williams and Wilkins, 2022) Ucer O.; Erbatu O.; Albaz A.C.; Temeltas G.; Gumus B.; Muezzinoglu T.
    Objectives: The aim of our study was to compare the effects on quality of life (QoL) and stone-free rate (SFR) of percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS) in patients with renal stones 2-4cm. Materials and methods: A total of 102 patients with renal pelvis stones were enrolled in this prospective controlled study, of which 52 were performed RIRS and 50 with PNL. The QoL was evaluated by using Short From-36 pre- and post-operatively. Also, the surgical data of all patients during and after the operations were compared between the 2 groups. Results: The mean age, body mass index, stone size and density of the patients in the 2 groups were statistically similar (p>0.05). The SFR of PNL and RIRS were found 94% (47/50) and 73% (38/52), respectively (p<0.01). There were no statistically differences between operation times, minor complication rates and Short From-36 scores of the 2 groups. Hospitalization times were 1.13± 0.34days for RIRS and 2.9±5.7days for PNL (p<0.05). While the blood transfusion rate of PNL group was 8% (4/50), none patient was made blood transfusion in RIRS. Conclusions: The results of our study show that the blood transfusion rates and hospitalization times of RIRS group are significantly lower than PNL for management of renal pelvis stone 2-4cm. Despite these advantages of RIRS, the SFR is significantly lower than PNL for these stones. The effects on QoL of the both interventions before and after surgery were similar. © 2022 S. Karger AG.
