“…This is consistent with another previous study by Alshoabi, who reported that calculi were the cause of HN in 60% of cases. 11 This study showed predilection of HN to male gender. This predilection was explained by the results of a previous study by Ahmed et al who reported that urinary tract calculi, which are the most common cause of HN, are formed more common in males due to hormonal effects.…”

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.

“…Failure of the urine excretion process is caused by an obstructive or nonobstructive process due to a functional or structural change of the urinary system. 1 The presentation of hydronephrosis can be unilateral or bilateral, physiologic or pathologic, and acute or chronic. 6 Each year, approximately 42,000 new cases of hydronephrosis are diagnosed with a two-to-one male-tofemale prevalence.…”

“…15,16 Hydronephrosis is graded on a scale from 0 to 4, 4 being the most severe, indicating increased renal cortex damage and decreased renal function. 1,7 The severity of hydronephrosis can be determined by evaluating the kidneys' sonographic features on a renal sonogram. Grade 0 is an absence of hydronephrosis in the collecting system and is visualized as normal-appearing kidneys.…”

This case study examines a patient with severe hydronephrosis caused by ureteral obstruction, secondary to ovarian serous carcinoma. Gynecologic malignancies, especially advanced ovarian carcinoma, are common extrinsic causes of obstructive hydronephrosis. Sonography is a valuable modality to visualize the kidneys, diagnose hydronephrosis, and determine the grade of hydronephrosis. The treatment of hydronephrosis aims to remove the build-up of urine, prevent permanent kidney damage, and treat the underlying cause. Prolonged or severe cases of hydronephrosis can lead to acute kidney injury.

“…7 The literature reported resistive index sensitivity and specificity, 75.5% and specificity 92.5% respectively. 8 Literature shows that the resistive index is influenced by many other factors such as the age of patient, level of renin in plasma, and the simultaneous presence of diabetes mellitus, hypertension, cardiac diseases, and variety of kidney disorders. The presence of any of these factors may rise the values of resistivity index even in there is no renal obstruction.…”

Objective: To study the correlation of resistive index of main renal artery and inter-lobar artery with degree of hydronephrosis. For the purpose of this study data collection was carried through different research works conducted previously regarding hydronephrosis and its effects on the resistivity index of renal arteries. Study Design: Systemic Review. Setting: Radiology Research Section, University of Lahore. Period: September 2018 to May 2020. Material & Methods: Research was conducted with the help of keywords. One hundred and three articles were found at initial stage. A table was designed for data collection purpose including the information such as author of article, year of research, type of hydronephrosis, number of patients, and the resistive index of renal arteries. The data included both male and female patients of any age suffering from hydronephrosis of any origin and no area or time limitation was applied. Results: Pooling results of this systematic review depicts that the researchers conducted various researches addressing the cause of hydronephrosis, the effect of type of hydronephrosis on the resistive index, difference between resistivity index of obstructive and non-obstructive hydronephrosis, level of obstruction and its effect on RI of the renal artery, factors that influence RI other than renal in origin but not a single research conducted on human subject represents the correlation of different grades or degrees of hydronephrosis with either main renal artery or inter-lobar arteries. Out of 17 articles, 8 (47%) articles discuss the resistive index for both obstructive and non-obstructive hydronephrosis while remaining 9 (53%) articles discuss only the mean resistive index for the obstructed kidney. Conclusion: Although renal resistive index is the parameter which is influenced by a variety of other factors such as age of patient, plasma renin level, and the simultaneous presence of certain diseases like hypertension, cardiac diseases, diabetes mellitus, and renal disorders. The presence of any of these factors may rise the RI values even if there is no renal obstruction. Yet different research mainly shows that the values of RI are high i.e. >0.70 in case of obstructed kidney while generally the values of RI are <0.70 in case of none obstructed kidney.
