The purpose of the present study was to determine whether pregnant women with pyelonephritis have differences of pelvicalyceal systems, compared with normal pregnant control subjects, that might predispose to upper urinary tract infection. Ultrasonographic examination of both kidneys in coronal and axial planes of 24 women with clinical pyelonephritis and positive urine cultures was compared with results in control subjects matched for gestational age, parity, and race. Women with right or bilateral pyelonephritis had increased dilation of the right calyceal system, compared with controls (1.7 cm vs 0.8 cm, p less than 0.001). Renal pelvis volume was increased as well (29.3 vs 5.5 cm3, p less than 0.001). Renal pelvicalyceal dilation in antepartum pyelonephritis was significantly increased compared with normal physiologic dilation of pregnancy. Follow-up nephrosonography in a small number of women (N = 10) after treatment of pyelonephritis did not reveal a consistent decrease in renal dilation, suggesting that dilation of the renal pelvis may antedate pyelonephritis. Further study of this phenomenon is warranted.

The study was carried at two different centres. Only 9 cases of primary malignant tumours of the renal pelvis could be collected during the period of 7 years (1984-1990). Renal pelvis malignancies constituted 0.21% of all the malignancies and 12.16% of all the malignant growths of the kidney (9 out of 74 cases). The age of these patients ranged from 24 to 70 years; the mean being 41.7 years. Male/female ratio was 8:1. Common triad of complaints (pain, haematuria and lump) was noticed in 22.2% of patients. Individually they were noticed in 77.8%, 66.7% and 44.4% of patients respectively. Transitional cell carcinoma was the commonest, seen in 7 patients (77.8%) whereas squamous cell carcinoma and adenocarcinoma were noticed in one patient (11.1%) each. Hydronephrosis, chronic pyelonephritis and nephrolithiasis were noticed in 66.7%, 44.4% and 22.2% of patients respectively. Ultrastructural study of urothelial tumours revealed tumour cells in various stages of differentiation with loss of intercellular junctions and dense collection of rough endopasmic reticulum fibrils around the nucleus.

We present an impressive case of a pregnant woman presenting with severe right flank pains. A rare rupture of the right renal pelvis turned out to be the cause of her problems. Renal pelvis rupture in pregnancy is difficult to diagnose. It is easily confused with other more prevalent diagnoses, like hydronephrosis, ureteral distension, renal calculus and pyelonephritis. Ultrasonography is not always conclusive. Pyelography seems to be a good diagnostic tool, this case shows that MRI is another option. Renal pelvis rupture can be effectively treated with the insertion of a JJ-stent.
