What is the best approach for pediatric kidney stones of moderate-sized between shock wave lithotripsy, ultramini percutaneous nephrolithotomy and retrograde intrarenal surgery?

PURPOSE: This study aimed to compare the results of ultramini percutaneous nephrolithotomy (UMP), shock wave lithotripsy (SWL) and retrograde intrarenal surgery (RIRS) in pediatric patients with kidney stones 10-20 mm size. METHODS: The files of 159 pediatric patients (36 RIRS, 39 SWL, 84 UMP) with kidney stones were reviewed retrospectively. Preoperative age, sex, stone size and location were evaluated. The three methods were compared in terms of operation and fluoroscopy duration, complications with the modified Clavien grading system, and stone-free rate (SFR) in the postoperative first month. RESULTS: The stone burdens of the groups were similar (P = 0.102). At the end of the first month, SFR was higher in the RIRS and UMP groups compared to the SWL group (88.9%, 92.9% and 69.2%, respectively, P = 0.002). UMP had higher SFR for lower pole stones than the other two methods (P = 0.042). There was no difference in complications between the three methods (P = 0.758). CONCLUSION: SFR was similar for all three methods in all localizations, apart from lower pole stones. UMP had higher SFR for lower pole stones than the other two methods. There was no difference in terms of complications between the three methods.

Better outcomes with desmopressin melt than enuretic alarm therapy in children with nocturnal enuresis during coronavirus disease 2019 (COVID-19).

Objectives: This study aimed to investigate the effect of the coronavirus disease 2019 (COVID-19) pandemic on the treatment of children with primary monosymptomatic nocturnal enuresis (MNE) with desmopressin melt versus an enuresis alarm. Materials and methods: This study included 56 children with primary MNE who were taking desmopressin melt or using an alarm. Their anxiety levels were evaluated using the Social Anxiety Scale for Children-Revised. For both treatment methods, data from a 3-month bedwetting diary between the third and sixth months of the pre-pandemic treatment were compared with those assessed during the same period during the pandemic. Results: Prior to the COVID-19 pandemic, the median 3-month mean frequency of MNE was 1 (0-7.67) in children using desmopressin melt versus 1.33 (0-6) in those using alarm treatment (p = 0.095). During the COVID-19 pandemic period, the median monthly mean frequency of MNE was 1.33 (0-7.33) in children using desmopressin melt versus 6 (1.33-13) in those using alarm treatment (p < 0.001). Conclusions: The COVID-19 pandemic and its accompanying psychological effects did not affect the treatment efficacy of desmopressin melt in children with primary MNE but did adversely affect that of enuresis alarms.

Predictive Factors Affecting the Success of Nephrectomy for the Treatment of Nephrogenic Hypertension: Multicenter Study.

INTRODUCTION: The aim of our study is to evaluate the predictive factors affecting the success of treatment with nephrectomy in patients with poorly functioning kidney and nephrogenic hypertension. METHODS: Data for patients who underwent nephrectomy with a diagnosis of nephrogenic hypertension in 3 centers between May 2010 and January 2020 were analyzed. In the postoperative period, if the blood pressure (BP) was below 140/90 mm Hg without medical treatment, it was accepted as complete response; if the arterial BP was below 140/90 mm Hg with medical treatment or less medication, it was accepted as partial response; and if BP did not decrease to normal values, it was accepted as unresponsive. Demographic characteristics, duration of hypertension, preoperative and postoperative BP values, and presence of metabolic syndrome were statistically evaluated. RESULTS: Our study consisted of 91 patients with a mean preoperative hypertension duration of 23.3 ± 12.1 months. Among patients, 42 (46.2%) had complete response, 18 (19.8%) had partial response, and 31 (34.0%) had no response. Preoperative systolic and diastolic BP values were not effective on treatment success (p = 0.071, p = 0.973, respectively), but the increase in age and hypertension duration (p = 0.030 and p < 0.001, respectively) and the presence of metabolic syndrome (p = 0.002) significantly decreased the complete response rates. CONCLUSIONS: Preoperative hypertension duration, advanced age, and presence of metabolic syndrome are predictive factors affecting the response to treatment in patients who undergo nephrectomy due to nephrogenic hypertension.

The role of RENAL, PADUA and C-index scoring systems in predicting the results of partial nephrectomy without ischemia.

OBJECTIVE: To evaluate the feasibility and renoprotective effect of off-clamp partial nephrectomy (PN) by renal scoring systems. METHODS: After approval of the local ethics committee, the radiological and clinical data of patients with renal masses who underwent PN between January 2012 and January 2017 were evaluated in two university hospitals. Total 132 patients who underwent open surgery and off-clamp technique were included. All patients underwent contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) preoperatively. Preoperative demographic data, estimated glomerular filtration rate (e-GFR) and hematocrit changes, operation time, tumor volume and hospitalization time from patients were evaluated separately and statistically for each of the three scoring systems. RESULTS: Our study consisted of 132 patients with a mean age of 53.9 ± 13.9 with 69 male and 63 female. Statistically significant difference between the risk groups in RENAL and PADUA scoring were found according to tumor T stage and tumor volüme (p <0.005). Statistically significant difference was only found between risk groups of RENAL scoring system in e-GFR reduction (p<0.05). There was no statistically significant difference between the groups in the complications of all three classification systems (p > 0.005). CONCLUSIONS: In our study, all three scoring sytem successfully predicted the surgical complexity ve surgical outcomes and our results indicate that off-clamp PN has similar success and complications rates when compared to the literature. The off-clamp PN must be kept in mind to maintain postoperative renal functions eligible patients.

Small renal pelvis stones: Shock wave lithotripsy or flexible ureteroscopy? A match-pair analysis.

OBJECTIVE: Kidney stones in renal pelvis may be treated using various methods. For larger stones, percutaneous nephrolitotomy (PNL) is the first choice of option; where for smaller stones, shock wave lithotripsy (SWL) or flexible ureteroscopy (F-URS) could be more suitable options. In this article we aimed to compare the outcomes of F-URS and SWL on the treatment of renal pelvis stones <10 mm. MATERIAL AND METHODS: Files of patients treated with SWL and F-URS for renal pelvis stones <10 mm between March 2013 and May 2016 in our clinic were analyzed. For comparison, a match-pair analysis was designed. Complete stone removal was considered success. RESULTS: Forty patients were treated using F-URS (Group 1) and 40 patients underwent SWL (Group 2). Patients were assessed the day after the last session of the procedure. The early stone-free rates were 70% (28/40) in Group 1, and 15% in Group 2 (p<0.05). The same analysis was performed after three months. Stone-free rates were 100% and 92.5% in Groups 1 and 2, respectively (p=0.079). Three patients in Group 2 were not stone free after 3 sessions of SWL and considered unsuccessful. They were all successfully treated by F-URS. CONCLUSION: Even though there is no statistical difference among groups, our data may be interpreted as having better outcomes and tolerability with F-URS than SWL. We believe F-URS may have a great treatment prospect in this particular patient group.

Conservative/surgical treatment predictors of maternal hydronephrosis: results of a single-center retrospective non-randomized non-controlled observational study.

PURPOSE: To determine the parameters that may help the clinicians decide the best suitable treatment method for the pregnant women with symptomatic hydronephrosis which will be based on the easily accessible laboratory tests, monitoring methods and clinical symptoms. METHODS: Digital data and documents of 246 pregnant women with symptomatic hydronephrosis who were hospitalized in our clinic between the dates of January 2011 and January 2016 were retrospectively evaluated. All patients were statistically evaluated in terms of age, symptomatic maximal anterior-posterior diameter of the renal pelvis (MADP), parity, C-reactive protein (CRP) level, white blood cell count (WBC), presence of pyuria, growth of urine culture, fever, serum urine and creatinine levels, visual analog scale (VAS) score of pre- and post-therapy and threatened preterm labor. RESULTS: The study includes a total of 211 pregnant women with symptomatic hydronephrosis. In the second and third trimester groups, the surgical treatment group statistically provided higher levels of CRP, WBC and VAS. Mean MADP in the second trimester of the conservative and surgical groups where symptomatic hydronephrosis was on the right side was 16.67 ± 4.67 and 28.68 ± 7.70 mm, respectively. Mean MADP in the third trimester group of the conservative and surgical groups where symptomatic hydronephrosis was on the right side was 16.96 ± 5.96 and 28.85 ± 7.64 mm, respectively. CONCLUSIONS: In patients with symptomatic pregnancy hydronephrosis, the likelihood of surgical treatment for CRP levels, WBC counts and VAS is high.
