THE COMPARATIVE STUDY TO DETECT RENAL & URINARY TRACT CALCULI (NEPHROLITHIASIS AND UROLITHIASIS) ON ULTRASOUND AND CT.

Background: Ultrasound is a non-invasive imaging modality, and it is cost effective while CT in invasive that uses ionizing radiations, yet it is difficult on ultrasound to diagnose calculi in ureter hence for evaluation of ureteric calculi CT scan is gold standard modality. Objective: To compare the detection of renal& urinary tract calculi (nephrolithiasis & urolithiasis) on ultrasound and CT. Material and methods: The data bases PubMed, ProQuest, and Google scholar and research gate were searched with the key words: nephrolithiasis on ultrasound and CT, sensitivity, specificity, from 2010 to 2021. For inclusion and exclusion of studies independently screened the titles and abstracts of full and related articles. Articles that had information about nephrolithiasis, urolithiasis at ultrasound and CT and its sensitivity and specificity were included. Results: In total, 28 studies were found on renal & urinary tract calculi at ultrasound and computed tomography. This literature review demonstrates that computed tomography is characterized by high sensitivity and specificity in diagnosing renal, ureteric calculi while ultrasound has low sensitivity and specificity. Conclusions: Ultrasound is the best modality for imaging calculi within the kidney, a well hyper echoic mass with posterior acoustic shadow is identified as stone on gray scale, color Doppler can be used for demarcation of stone. At Color Doppler twinkling artifact appears around the calculi hence it can be differentiated by hyper echoic renal sinuses but this is crucially dependant on the size and anatomical position of the stone. The ultrasonic evaluation either overestimates or misinterprets the calculi size while CT gives an exact measurement, position with authentic sensitivity and specificity. Hence, CT is the gold standard for detection of renal calculi. Recommendation: Ultrasound is a non-invasive imaging modality and it is cost effective while CT in invasive that uses ionizing radiations, yet it is difficult on ultrasound to diagnose calculi in ureter hence for evaluation of ureteric calculi CT scan is gold standard modality.

Bilateral Synchronous 3-port Transperitoneal Laparoscopic Ureterolithotomy: A Case Report

Transperitoneal laparoscopic ureterolithotomy is a well-established minimally invasive procedure for management of large impacted ureteric stones since the last 3 decades. We present a case of a 51 years old gentleman, who presented with bilateral large upper ureteric calculi with obstructive uropathy and azotemia, managed successfully with bilateral synchronous 3-port transperitoneal laparoscopic ureterolithotomy, and to our knowledge is the first such case to be reported in literature.

A Prospective Study on Evaluation of Efficacy of Combination Therapy of Tamsulosin and Deflazacort In Ureteric Stone Expulsion

The patients with ureteric stone are increasing day by day all over the world. A ureteric stone is a mineral mass in the ureter which may or may not originated in the kidney and travelled down to the ureter. The presence of stone in ureter causes inflammation and edema. There are mainly four types of ureteric stone such as Calcium stones, Uric acid stones, Struvite stone, Cystine stone. About 23-53% of spontaneous stone expulsion occurs where the size of stone is 5-10mm diameter. Tamsulosin is an alpha 1 adrenergic blocker which has a spasmolytic action and thus hasten stone expulsion. Deflazacort is a corticosteroid prodrug which acts on the glucocorticoid receptor to show an anti-inflammatory effect. Deflazacort decreases the edema and when prescribed along with alpha 1 adrenergic receptor blocker it facilitate the expulsion of calculi. This study was conducted in 20 patients diagnosed with ureteric calculi. The study was conducted by using suitable proforma for collecting various data’s like site of stones, presence of hydronephrosis, signs and symptoms. Health related quality of life of the patients with ureteric calculi under the treatment of Tamsulosin and Deflazacort combination were assessed by using Wisconsin Stone-QOL questionnaire. As counselling aid patients information leaflet was provided. The patients were asked to review after 10 days of taking the medication. At the end of the study all the parameters and scores were compared with baseline to the end of the study. In our study we analyzed that the data collected from 20 patients diagnosed with ureteric calculi accessed the improvement of quality of life of patients under the treatment of Tamsulosin and Deflazacort combination by using Wisconsin Stone-QOL questionnaire. The observed difference before and after the treatment with Tamsulosin and Deflazacort w

Etiology of Hydronephrosis in adults and children: Ultrasonographic Assessment in 233 patients

Objectives: Hydronephrosis (HN) is dilatation of the collecting system of the kidney due to obstruction of urine outflow. This study intended firstly, to investigate the efficacy of ultrasound (US) imaging to determine the cause of HN, and secondly, to list the causes of HN. Methods: In this retrospective study, 233 patients with HN were scanned to determine the cause of the HN in the period from 1st January 2016 to 31st October 2017. Categorical results were written as frequencies and percentages. Results: Out of 233, 91.41% were adults and 8.58% were children (P<0.001), 66.10% were male and 33.90% were female (P<0.001). In 55.36%, HN was in the right kidney and 44.64% was in the left (P=0.116). Exactly 58% of patients were suffering from grade-2, 21.5% grade-3, 11.6% grade-1, and 8.2% grade-4 HN. US imaging can determine the cause of HN in 70.4% of patients. Kidney or ureteric calculi were the cause of HN in 54.1% of cases, reflux was in 7.3%, and pelviureteric junction (PUJ) stenosis was in 3.9%. In cases of calculi induced HN, 25.3% of the calculi were in the vesicoureteric junction (VUJ), 21.5% were in the renal pelvis, 6.4% were in the PUJ or upper ureter, and only 0.9% were in the middle ureter. Conclusion: Ultrasound imaging can determine the cause of HN in more than two thirds of patients. Calculi are the most common cause of HN even in children and are most common in the VUJ.

CLINICAL PROFILE AND COMPARISON OF OUTCOME OF TREATMENT BY EXTRACORPOREAL SHOCK WAVE LITHOTRIPSY AND URETERORENOSCOPY IN THE MANAGEMENT OF UPPER URETERIC CALCULI

Objective: Urinary calculi are the third most common affliction of the urinary tract, exceeded only by urinary tract infections and pathologic conditions of the prostate. This study was carried out to assess the safety, efficacy, and compare structural and functional outcome after treating the patients of the upper ureteric calculus with Extracorporeal Shock Wave Lithotripsy (ESWL) and Ureterorenoscopy (URS). Methods: A prospective study was conducted on patients with the upper ureteric stone of size 0.5–1.5 cm. A total of 50 patients were included in the study by means of systematic random sampling so as to get 25 patients in each category of ESWL and URS for the treatment of their upper ureteric calculi. Results: The age ranged from 15 years to 55 years. There were 36 males and 14 females in the study of 50 patients, 43 (86%) presented with pain, followed by 4 (8%) presented with hematuria. Twenty-eight (56%) of the patients had stone in the range of 0.5–1.0 cm, and 22 (44%) of the patients had stone in the range of 1.0–1.5 cm. Sixteen (32%) patients had stone within 2 cm of the pelvi-ureteric junction, and 13 (26%) had stone within 2 cm of the sacroiliac joint. Twenty-one (42%) patients had stone in between these two. Of the 50, 25 patients (50%) underwent shock wave lithotripsy, 25 patients (50%) underwent URS. In the ESWL group, 21 (84%) patients were stone-free after single sitting of ESWL. Four patients (16%) who required Re ESWL, after repeat ESWL two became stone-free however 2 (8%) patient of 1.0–1.5 cm category required secondary procedure, that is, URS and became stone free. To achieve stone-free 1.24 procedure was required per patients. Of the 25 patients in the ESWL group, 2 (8%) patient (one steinstrass case and one poor fragmentation case) required secondary procedure. They underwent URS. Both the patient belonged to 1.0–1.5 cm group. URS was done using semirigid ureteroscope using pneumatic Lithoclast. In our study, two patients of each 0.5–1.0 cm and 1.0–1.5 cm category did not become stone free. These four patients were subjected to ESWL and became stone free. Conclusion: The management of the ureteral stone should be decided on individual basis, based on stone size, location, symptoms, obstruction, and the availability of the instruments. For stones of 0.5–1.0 cm, ESWL is the treatment of choice for the upper ureteric stones, with very low Re- ESWL (1.12 sittings) without any requirement of ancilliary procedure. URS may be used for the upper ureteric stones but requirement of ancilliary procedure is high 11.11%. For stones between 1.1 cm and 1.5 cm, ESWL is the preferred modality of treatment for the upper ureteric stones.

Surgical management of spontaneously ruptured kidney with peritonitis due to neglected renal and ureteric calculi

A 30-year-old woman presented with right-sided abdominal pain associated with fever. Her ultrasound showed right renal calculus with no hydronephrosis along with collection in peritoneal cavity and pouch of Douglas. CT showed ruptured right kidney with multiple renal and ureteric calculi as well as displaced renal calculi in perinephric space and pararenal space. Exploratory laparotomy and right nephroureterectomy were done. Nephrolithiasis with secondary infection makes the kidney fragile due to pathological changes, which may cause rupture of the renal calyces with trivial trauma or may be spontaneous. Distal obstruction by the stone and increased back pressure in the calyces may have added to the spontaneous rupture of the calyx and subsequently renal parenchyma. Management includes early exploration with nephrectomy and it is often life saving.

EVALUATION OF EFFICACY OF SILODOSIN VERSUS SILODOSIN WITH DEFLAZACORT IN EXPULSION OF LOWER URETERIC CALCULI

Objectives: To compare the efcacy of silodosin versus silodosin with deazacort in expulsion of lower end ureteric calculi, in terms of episodes of pain,stone expulsion rate,stone expulsion time ,analgesic requirements and side effects Introduction: Ureteric calculi represent 20% of urinary stones. Ureteroscopy and Shock wave lithotripsy proven the method of treatments for lower ureteric stones; however, they are expensive and not risk free. Aconservative approach is becoming more popular as a result of advances in pharmacological therapy which reduces the symptoms and helps in stone expulsion. We performed a randomized controlled prospective study to evaluate the efcacy of Deazacort in combination with alpha blocker silodosin in medical management of symptomatic lower Ureteric stones of ≤8 mm size. Material and methods: A prospective randomised controlled study was conducted on 60 patients, age ≥ 18 , who had unilateral lower ureteric stone of ≤ 8 mm. Patients were divided into three groups. Group 1 received silodosin 8 mg for 14 days,Group 2 received silodosin 8 mg plus deazacort 30mg daily for 14 days and Group 3 (control) received diclofenac potassium (75 mg ) when required. The patients were followed-up by ultrasonography ,plain radiograph KUB and computed tomography (in some cases). Results: There was a higher stone expulsion rate of 95% in Group 2 as compared to Group 1(85%) and Group 3(35%) . Group 2 showed a signicant advantage for stone expulsion time ,decreased pain episodes and analgesic use. Two patients, one in group 1 and group 2, reported retrograde ejaculation. Conclusion: The results showed that silodosin with deazacort , increases the stone expulsion rate, decrease the stone expulsion time, decreases the mean number of pain episodes and decreases the mean analgesic dosage requirement. But larger study is required to establish its efcacy for expulsion rate which will be statistically signicant.

Retrograde intrarenal surgery or percutaneous nephrolithotomy in the treatment of impacted proximal ureteric calculi

The objective of this study was to compare the clinical efficacy of retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) in the treatment of impacted proximal ureteric calculi. This was a retrospective study on surgical outcomes of 202 patients with impacted proximal ureteric calculi. Overall, 140 and 62 were treated with RIRS and PCNL, respectively. The effects of the choice of the surgical method on the surgical outcomes were evaluated by preoperatively scoring patients with high-risk factors related to stone characteristics and analyzing these scores. Compared to the RIRS group, the surgical duration of the PCNL group was significantly shorter (51.69 ± 25.07 min vs. 67.46 ± 27.12 min, p < 0.05), stone-free rate (SFR) was significantly increased (98.4% vs. 72.10%, p < 0.05), and total treatment cost was lower (US $1678.61 ± 714.86 vs. US $3901.45 ± 1069.46, p < 0.05). Preoperatively, the efficacy of PCNL was higher than that of RIRS based on the higher scores observed. The results indicated PCNL had a better SFR and higher surgical efficacy, whereas RIRS had higher surgical safety parameters, a shorter perioperative period, but a lower initial SFR. PCNL is often more advantageous for complicated impacted proximal ureter stone.

Covid-19: A Double Edged Sword-Rise in Complicated Ureteric Stone Disease

Introduction: Healthcare is facing one of the biggest challenges in the form of Coronavirus-19 pandemic. Various measures are taken by the government to curb its spread in the form of lockdowns, travel bans, and restrictions upon non-covid admission to assimilate resources to tackle pandemic has affected non-covid patients in the form of delayed treatment. Ureteric calculus can present acutely and in sub-acute forms but without proper treatment in due time may have serious consequences. In our study, we aim to investigate the effect of pandemic upon patients of ureteric calculi.
