“…When comparing Intra-Uterine Growth-Restricted (IUGR) fetuses with Appropriate weight for Gestational Age (AGA) fetuses at the same gestational age, the HFUPR was significantly lower for IUGR fetuses (Nicolaides et al, 1990;Takeuchi et al, 1994;van Otterlo et al, 1977;Wladimiroff and Campbell, 1974). However, there were no significant differences when the IUGR fetuses were compared with controls of corresponding body weights but with lower gestational ages (Wladimiroff and Campbell, 1974).…”

“…It was assumed that the reduced urine production rate for IUGR fetuses reflected renal hypoplasia, due to growth retardation. Although different investigations have presented various normal values, the HFUPR in IUGR fetuses compared with fetuses of normal size (AGA) has generally been reported to be lower (Nicolaides et al, 1990;Takeuchi et al, 1994;van Otterlo et al, 1977).…”

“…The Hourly Fetal Urine Production Rate (HFUPR) can be estimated by regression analysis of calculated bladder volumes documented at different time points within one filling phase (Campbell et al, 1973;Fagerquist et al, 2001;Groome et al, 1991;Nicolaides et al, 1990;Rabinowitz et al, 1989;van Otterlo et al, 1977;Wladimiroff and Campbell, 1974), or by the difference between the maximum and minimum volumes divided by the time interval (Deutinger et al, 1987;Shin et al, 1987;Takeuchi et al, 1994). The filling and emptying dynamics of the fetal urinary bladder have been investigated in detail.…”

“…With increasing investigative modalities, more cases of bilateral multicystic kidney are diagnosed antenatally [14]. Significant decreases in foetal urine production have been reported as evident in bilateral renal agenesis (100%) at 21-23 weeks; bilateral infantile polycystic kidney (100%) at 21-28 weeks; bilateral multicystic kidney disease (100%) at 21-31 weeks and bilateral hydronephrosis (60%) at 21-38 weeks [15].…”

Aim was to describe the challenges faced in the management of bilateral multicystic kidney disease (MCKD). A case of antenatally detected bilateral polycystic disease was referred at 28 weeks of gestation. The patient was advised to continue pregnancy till term and be in regular follow-up. Postnatally, the male baby passed urine in normal stream and was diagnosed as bilateral multicystic kidney disease on ultrasonography. He developed symptoms of renal failure. The baby was operated with right pyeloplasty and left pyelostomy, as the left ureter was atretic. The histopathology was consistent with bilateral multicystic kidney disease. Postoperatively, the baby was stable with intermittent episodes of metabolic acidosis that were managed medically and with peritoneal dialysis. Autologous stem cells were injected at the age of 1 year into the aorta at the level of the renal arteries clamping the aorta below. Repeat biopsy at time of stem cell injection showed 5/10 glomeruli showing global sclerosis on right side and 5/15 glomeruli showing global sclerosis on left side. The only improvement seen was in decreased doses of medicines to keep the child metabolically stable. The baby kept struggling but succumbed at the age of 17 months and 15 days. Post mortem bilateral renal biopsies demonstrated presence of primitive renal tubules and blastemal cells that were not demonstrated earlier. Survival for few months in bilateral multicystic kidney disease is thus possible with adequate treatment, the novel use of stem cells in these cases may prove beneficial in future though it is too early to comment further.

“…41 mm without such findings as either thickening of the wall or deformity [7]. Although amniotic fluid volume was normal with a pocket measurement of 3 cm in depth [8], no fetal micturition was found throughout continuous observation of the urinary bladder, for a 120-min period [9]. Hence, we attempted to simultaneously observe, while measuring both the anteroposterior dimension of the right renal pelvis and the ellipse size of urine-filled bladder area once every minute for 40 min.…”

We report a case with vesicoureteral reflux (VUR), diagnosed antenatally. A 31-year-old Japanese woman was referred at 37 weeks’ gestation because of the fetus having unilateral renal pelvis dilatation. The real-time ultrasound revealed a right renal pyelectasia with periodic changes in size over intervals lasting several minutes. The simultaneous examinations of both anteroposterior dimension of the renal pelvis and the ellipse size of urine-filled bladder area demonstrated that they varied in size in a reciprocal fashion, leading us to diagnose the fetus as having VUR. Postnatally, bilateral VUR was confirmed by the voiding cystogram. This case has typical ultrasonographic findings of fetal VUR, in which both the renal pelvis and urinary bladder dimensions change periodically in a reciprocal manner with each other, when the reflux really occurred.
