ABSTRACT
Objectives: To compare operative times, safety, and effectiveness of percutaneous nephrolithotomy in the supine versus the prone position. Materials and methods: An observational study of 100 patients was conducted in our institution for 2years from 2018 to 2020 divided into 2 groups: 50 patients underwent modified supine percutaneous nephrolithotomy (PCNL) and 50 patients underwent standard prone PCNL. The inclusion criteria included a renal calculus (calyx or pelvis) of any size for which PCNL was indicated and exclusion criteria were patients having contraindications for PCNL such as bleeding disorders, pregnancy, high risk, and co-morbid conditions. The measured data included operative time, number of punctures, stone-free rate, length of hospital stays, and rate of complications. Results: The 2 groups were comparable in mean age, male to female ratio, calculus size, number of punctures, residual calculi, and postoperative fever and pain. The mean difference of hemoglobin in the supine PCNL group was 0.37 g/dL whereas in the prone PCNL group it was 0.61 g/dL. The p value was significant at 0.043. The mean time to finish from initial postion was 72.24 minutes in supine PCNL and 88.12 minutes in prone PCNL. The p value was significant (p < 0.001). The mean time before puncture was 20.92 minutes in the supine position and 31.84 minutes in the prone position. The p value was significant (p < 0.001). The mean time from puncture to finish was 51.32 minutes in the supine position and 56.28 minutes in the prone position. The p value was significant (p < 0.001). Conclusions: As observed from this study, supine PCNL is associated with a significantly reduced operating time when compared to conventional prone position PCNL procedures. The postoperative complications such as pain and fever were not significantly different. Hence, the supine PCNL is an equally effective modality for treatment of a renal calculus with benefits of simultaneous retrograde access and less operative time compared to the prone PCNL.
ABSTRACT
CONTEXT: Use of conventional double j stent with string and single loop stent with string after ureterorenoscopy. AIM: The aim of this study was to compare the use of both types of stents using the Ureteral Symptom Score Questionnaire (USSQ) and assess proximal migration. SETTINGS AND DESIGN: This was a single institute study. SUBJECTS AND METHODS: A total of 96 female patients with unilateral ureteric stones were enrolled. Patients underwent ureterorenoscopic lithotripsy, conventional double J (DJ) stent with string and single loop stent with string was placed. Before stent removal at 7-10 days, they were evaluated with X-ray kidney ureter bladder for proximal migration and USSQ for stent-related complaints. STATISTICAL ANALYSIS USED: Data were analyzed using Chi-square and Student's t-test. RESULTS: In our study, Group A (DJ loop with string) had 51 patients and Group B (single J loop with string) had 47 patients. The mean stone size in group A was 10.06 mm and Group B was 9.7 mm. Both groups had one case each of early stent expulsion and none had proximal migration of the stent. Group A had two cases of urinary tract infection and Group B had one case which resolved on antibiotics. Evaluating the USSQ questionnaire in both groups, urinary symptoms such as urgency (P = 0.03), dysuria (P = 0.02), interference with life (P = 0.01), and quality impact overall (P = 0.016) were statistically significant. Evaluating pain, sleep disturbance (P = 0.04), pain at voiding (P = 0.03), and flank pain during voiding (P = 0.018) was statistically significant. In general health, difficulty with heavyweight physical activity (P = 0.02), feeling calm (P = 0.16), social life enjoyment (P = 0.26), and need for extra help (P = 0.008) was significant. In sexual matters, 13 (28%) patients in Group B had no active sex (conscious) and 6 (12%) patients had stopped intercourse due to stent-related symptoms, whereas in Group A, it was 10 (20%) and 2 (4%) patients, respectively. CONCLUSIONS: The use of a single J stent with string is an effective method, has lesser complication, and is easier to remove.
ABSTRACT
INTRODUCTION: With significant advances in the area of interventional radiology, angioplasty and stenting have become preferred first-line treatment in patients with significant renal artery stenosis. However, not all patients have favorable anatomy to undergo minimally invasive treatments, and reconstruction of the renal artery is an option. In select cases, either improved renal function or maintenance of existing function and sometimes resolution of hypertension can follow surgical treatment. MATERIAL AND METHODS: This was a prospective observational study conducted from August 2010 to June 2016. Patients <45 years of age with uncontrolled hypertension secondary to renovascular hypertension (RVH) and refractory to medical management and renal arterial disease unfavorable for percutaneous intervention were included in the study. All patients were evaluated thoroughly using computed tomography angiography and diethylenetriaminepentaacetic acid renal scan. Patients underwent autotransplantation either into the right or left iliac fossa. Some kidneys required bench reconstruction of the renal artery and/or its branches before being implanted into either iliac fossa. RESULTS: Nine patients were included in the study. The mean age was 27 years. Seven were males and two were females. Five patients had bilateral renal artery stenosis. After autotransplantation, initially five patients became free of antihypertensive medicines, but on the follow-up, two patients showed rising trend of blood pressure. The evaluation revealed narrowing at anastomosis site in both patients with salvageable kidney function in one patient. Angioplasty with stenting was done in this patient while the second patient underwent secondary nephrectomy. At 2 years of follow-up, four patients required no antihypertensive medicines. CONCLUSION: Autotransplantation can be a successful treatment of severe RVH and should be considered in patients with renal arterial disease unfavorable for percutaneous intervention.
ABSTRACT
PURPOSE: To review our success in PCNL for managing large horse shoe kidney stones as primary treatment. METHOD: Between 2012 and 2016, a total of 23patients (24 renal units) underwent percutaneous renal surgery for stone dieses in horseshoe kidneys. Indications were HSK with stone more than 1 cm in size and failed ESWL. RESULTS: Mean age was 35.60 ± 10.10 years out of which 18 were males and 5 females. One patient had stone in both kidneys. Mean stone size was 22.03 ± 10.33 mm. Access site was upper calyceal and subcostal in all patients. In 2 patients an extra middle calyceal puncture were used for total clearance (8.69%). Mean operation time was 67.22 ± 7.63 minutes. One patient with staghorn stone was converted to open surgery because of inaccessibility of the stone and complexity of the renal calyceal system. Post operatively, 2 renal units with residual stone more than 8mm were cleared with ESWL. Complete clearance was achieved in 21 renal units with PCNL (87.50%). There was no significant intra operative complication. Post operatively 2 patients developed fever which was treated conservatively(clavien grade I). CONCLUSION: PCNL can be recommended as first line of management in the treatment of horseshoe kidneys with large stone burden considering its higher clearance rate and minimal complications.
ABSTRACT
AIM: The aim of this study is to compare the outcomes of miniaturized percutaneous nephrolithotomy (mini-perc) and retrograde intrarenal surgery (RIRS) in management of renal stones with a diameter <15 mm. MATERIALS AND METHODS: This was an open-label prospective study that included a total of 80 cases underwent mini-perc (n = 40) and RIRS (n = 40) between July 2014 and August 2017. The primary outcome objective was stone-free rate, retreatment rate, complications, hospital stay, operative time, and reduction in hemoglobin level. Data were analyzed using SPSS version 16.0 Software. RESULTS: Overall, 80 patients were enrolled in this study. The mean age was 40.12 and 38.20 years, and the mean stone size was 1.15 and 1.30 cm in mini-perc and RIRS group, respectively. Majority of the study participants were males. Overall, mini-perc and RIRS had stone clearance rates of 100% and 95.4%, respectively. Two patients required retreatment in RIRS group. The duration of hospital stay and the rate of complication was similar in both the groups. Operative duration was more in RIRS group. Decrease in hemoglobin level was more in mini-perc group. CONCLUSIONS: Results demonstrated that both modalities were associated with high stone clearance rates with minimal complications. RIRS was associated with less reduction in hemoglobin and could be used as standard treatment modality for small renal calculi.
ABSTRACT
INTRODUCTION: Children with urolithiasis are associated with considerable morbidity and commonly associated with metabolic abnormalities. By treating these abnormalities stone formation is prevented. OBJECTIVES: To study the metabolic risk factors of urolithiasis in children and compare them with literature. MATERIALS AND METHODS: In open, prospective and observational study, 75 children were evaluated from August 2010 to June 2014. In all patients' dietary history, water intake and results of laboratory findings were recorded. All urine samples obtained from patients were without dietary restrictions. Reference paediatric 24 hour urinary parameter was used according to western literature. RESULTS: We investigated 75 patients with urolithiasis. Low urine volume was found in 49 patients which is comparable with previous studies indicating simple intervention as to increase water intake. Low calcium intake was found in 44 patients suggesting that low calcium intake is associated with higher incidence of urolithiasis due to increased intestinal oxalate absorption. Hypocalcaemia was found in 32 patients and 24 hour urinary abnormality was found in only 16 patients'. Both these finding does not support previous literature. Stone analysis finding does not correlate with urinary finding. CONCLUSIONS: Low urine volume secondary to low water intake is predominant finding. Hypocalcaemia is major metabolic abnormality in contradiction to western literature. There are no nomograms for urinary excretion of Calcium, uric acid, oxalate and citrate in Indian children. Keeping the optimum blood calcium level & increased fluid intake can prevent stone formation in children.
ABSTRACT
Infantile colic in exclusively breastfed infant is very common. The mother in this situation gets panickyand under stress. This is very common emergency in paediatric hospital. Infantile colic is characterised by paroxysms of uncontrollable crying in an otherwise healthy and well fed infants younger than three months of age, more specifically infantile colic is defined as cry exceeding 180 minutes per 24 hours on 3 days in the week in first 3 months of life. The incidence of infantile colic is 5 to 19% in different studies. The mothers' description of this condition is that the breastfed baby who has been apparently alright in the day, frowns, his face becomes red, draws up his legs, screams, continues to cry for about 2 to 20 minutes and then attack ends suddenly. Episodes of cry are usually clustered in the late evening and early morning hours, which may cause significant disruption of family interactions. To find out the any supportive cause for infantile colic pertaining to maternal diet, we have conducted a study, where 110 crying infants were examined who happened to attend paediatric department over a period of one year. In this study it was found that more infants (50%) were in the age group >2-3 months, then >1-2 months (39.09%). Most of the patients happened to attend in casualty hours (5PM-9 AM) than in OPD hours (9 AM - 5 PM). Most cases (30.9%) took pulses in last 48 hours, followed by buffalo milk (20%). Most mothers (n=34) took pulses in diet in last 48 hours. It can be concluded that protein rich diet in one of the factor causing infantile colic.
