“…Physiologic hydronephrosis can occur in 90% of right kidneys and up to 67% of left kidneys during pregnancy. 4 The predominance of right upper tract dilation compared with the left may be caused by a combination of various factors including preferential compression of the right ureter because of uterine dextrorotation and protection of the left ureter by the gas-filled sigmoid colon. It is not uncommon for some pregnant women to experience greater pain relief when placed in the left lateral position.…”

Nephrolithiasis during pregnancy can represent a clinical dilemma because of potential risks to both mother and fetus. While the incidence of symptomatic nephrolithiasis during pregnancy varies between 1 in 244 to 1 in 2000 pregnancies, the actual incidence is likely to be higher. A significant proportion of patients with asymptomatic renal calculi are detected incidentally in the nonpregnant population compared with pregnant women. Factors that contribute to the diagnostic challenges include anatomic and physiologic changes to the female urinary tract during pregnancy and the limitations on the use of ionizing radiation. The treatment of such patients requires a multidisciplinary team approach involving the urologist, obstetrician, and radiologist. The potential hazards of intervention (either surgical or medical) and anesthesia need to be considered carefully.

BACKGROUND Pregnancy is associated with lower urinary tract symptoms which may affect the quality of life of the patients. Labour, delivery and various obstetric factors can influence these symptoms. The present study aims to evaluate the prevalence of lower urinary symptoms in pregnancy and the effect of obstetric factors on it. METHODS Seventy five primigravidas were followed up antenatally from 28 weeks of gestation till 6 weeks postpartum regarding urinary symptoms and quality of life using International Prostate Symptom Score. Data regarding obstetric variables like mode of delivery, birth weight of baby, duration of second stage of labour were collected. RESULTS The incidence of UTI was 26.6%. The symptom score showed 84% in the mild group and 16% in the moderate group. After delivery and 6 weeks postpartum, the symptoms and the quality of life score improved. There was no association between mode of delivery, duration of second stage, birth weight and episiotomy with the persistence of symptoms. CONCLUSIONS Most of the lower urinary tract symptoms developing during pregnancy resolve postpartum and obstetric factors are not associated with it.

“…[6][7][8]11,12 In this study grading was based on the measurement of maximum intrarenal pelvis dilatation on a longitudal plane of section of the kidney. A separation of renal sinus echoes less than or equal to 5 mm was considered to be within normal limits for a fluid-filled renal pelvis.ll The etiology of hydronephrosis is complex and involves multiple variable factors.…”

Hydronephrosis Secondary to Bladder Distension

This study was undertaken to evaluate if distension of the urinary bladder can cause reversible distension of the pelvicalyceal system of the kidneys. Ultrasound examinations on 72 healthy individuals with distended bladders showed a 13.9% incidence of mild (Grade 1) and a 2.8% incidence of moderate (Grade 2) hydronephrosis which disappeared when the bladder was emptied. Altered ureteral peristaltic patterns resulting from elevated intravesicular pressure and anatomic changes at the ureterovesical junction may provide a physiologic explanation for the transient hydronephrosis observed. A finding of moderate or severe hydronephrosis irrespective of the degree of bladder distension should alert the sonographer to the likely presence of obstructive uropathy.
