IN 1953 one of us described partial resection of the kidney and renal pelvis in the treatment of large hydronephroses (Hjort, 1953). The present paper gives an account of the use of this method of treatment in a general surgical department over a period of 25 years.According to our view reconstructive surgery for hydronephrosis has 2 objectives. The first is removal of the primary cause of obstruction and the second is reconstruction of the physiological funnel-shape of the renal pelvis. Regardless of the type of obstruction in hydronephrosis, the kidney and renal pelvis are fundamentally altered as a result of long-standing back pressure. We suggest that the resulting change of shape has the effect of adding to the obstruction.According to the hypothesis which forms the basis for the present operation the funnelshape of the renal pelvis is essential for its emptying. The aim of the operation is to transform the hydronephrotic kidney and renal pelvis into a funnel at the expense of the lower pole of the kidney. The operation is, in principle, identical with the " resection orthopidique pyilo-renale ",

“…These strictures are described as being either organic or dynamic. Two types of dynamic stricture are described, the first of a spastic nature (Hanley, 1959;Anderson 1962;Lutzeyer and Simons, 1963) and the second as an adynamic segment of the ureter (Melick et al, 1961).…”

“…Percutaneous pyeloplasty (endopyelotomy) is an endourological alternative to open surgery. In patients with high ureteric insertion, lack of a dependent, funnel‐shaped PUJ impedes drainage [19]. In this condition the pelvi‐ureteric tissue should be incised by the endopyelotome, so that a more dependent PUJ can be created [20].…”

Dynamic gadolinium‐enhanced magnetic resonance urography for assessing drainage in dilated pelvicalyceal systems with moderate renal function: preliminary results and comparison with diuresis renography

administered, with a time-intensity curve of each kidney produced. Drainage was diagnosed by a clearly declining timeintensity curve and direct visualization of contrast medium within the ureter in several frames. High-grade or complete obstruction was diagnosed when drainage of contrast medium could not be detected. Gd-MRU results were compared with diuresis radionuclide (mercaptoacetyltriglycine, MAG3) renography within the same week. Unobstructive units detected by Gd-MRU were treated conservatively with a close follow-up by ultrasonography and radionuclide studies. RESULTSDiuresis MAG3 renography showed drainage in three dilated units and poor washout in five; in contrast, Gd-MRU showed drainage in seven dilated systems (three showed poor washout by MAG3), and obstruction in the remaining case. The unobstructed units detected by MRU under conservative treatment thus showed no further deterioration of renal function or progressive hydronephrosis in the subsequent follow-up (mean 18 months, range 15-23). CONCLUSIONThese preliminary results suggest that dynamic Gd-MRU is a useful noninvasive imaging method in distinguishing obstructive from unobstructive dilated systems, particularly in patients with hydronephrosis and reduced renal function.

“…This failure of anatomical regression has been attributed to progressive atrophy and fibrosis of the renal parenchyma, but with the advent of cineradiography it became clear that the whole of the pelvicaliceal system retained to a variable degree its power to contract. Attention has already been focused on the patency of the new pelvi-ureteric junction and on the satisfactory outflow from the renal pelvis following pyeloplasty (Hanley, 1959). Since the calices form an integral part of the emptying mechanism of the kidney, an attempt will be made in this investigation to evaluate their function in the surgically treated kidney.…”
