Chronic intestinal pseudoobstruction （CIPO） resulting from intestinal smooth muscle damage has presented in conjunction with ureterohydronephrosis and, more rarely, biliary dilatation （megacholedochus）. While the molecular pathogenesis is largely unknown, observed histopathologic features include widespread myositis, myocyte necrosis in the intestinal muscularis propria with subsequent atrophy and fibrosis, preserved myenteric innervations and little vasculitis. High dose immunosuppression usually results in resolution of symptoms with recovery of smooth muscle function, indicative of an autoimmune etiology. We report a patient with SLE who presented with intestinal pseudo-obstruction, ureterohydronephrosis and megacholedochus, and present images that illustrate megaviscera simultaneously involving all 3 visceral organs. Since the co-manifestation of all 3 is unusual and has been reported only once previously, we have termed this rare clinical syndrome generalized megaviscera of lupus （GML）. Although the SLE disease-activity parameters responded to aggressive immunomodulative therapy in our patient, clinical evidence of peristaltic dysfunction persisted in all involved viscera. This is a variation from the favorable outcomes reported previously in SLE patients with GML and we attribute this poor clinical outcome to disease severity and, most importantly, delayed clinical presentation. Since inflammation followed by atrophy and fibrosis are key aspects in the pathogenesis and natural history of GML, the poor response in our patient who presented late in the clinical course may be the result of ＇burnt out＇ inflammation with irreversible end-stage fibrosis. Thus, early recognition and timely initiation of treatment may be the key to recover visceral peristaltic function in patients with GML.展开更多

Renovascular lesions are involved in various nephropathies, and most renal diseases have an ischemic component that underlies the resulting renal fibrosis. The aim of this study was to investigate whether morphological changes occur in the renal vasculature in hydronephrosis and the possible mechanisms involved. A model of complete unilateral ureteral obstruction（CUUO） was used. Experimental animals were divided into five groups： a normal control group（N） and groups of animals at 1st week（O1）, 2nd week（O2）, 4th week（O4） and 8th week（O8） after CUUO. Blood pressure was measured, renal arterial trees and glomeruli were assessed quantitatively, and renovascular three-dimensional reconstruction was performed on all groups. Glomerular ultrastructural changes were examined by transmission electron microscopy. The results showed that the systolic blood pressure was significantly increased in the obstructed groups（O1, O2, O4 and O8）. Three-dimensional reconstruction showed sparse arterial trees in the O8 group, and a tortuous and sometimes ruptured glomerular basement membrane was found in the O4 and O8 groups. Furthermore, epithelial media thickness and media/lumen ratio were increased, lumen diameters were decreased, and the cross-sectional area of the media was unaltered in the segmental renal artery, interlobar artery and afferent arterioles, respectively. In conclusion, renal arterial trees and glomeruli were dramatically altered following CUUO and the changes may be partially ascribed to vascular remodeling. Elucidation of the molecular mechanisms of renovascular morphological alterations will enable the development of potential therapeutic approaches for hydronephrosis.展开更多

Chronic obstruction can ultimately lead to dysfunction of the affected kidney, and atypical presenting symptoms create pitfalls in diagnosis. Few reviews in the literature focus on this process and are limited to isolated case reports and case reviews. We performed a PubMed search using such terms as “Hydronephrosis” AND “Crohn’s disease” AND/OR “ureteral obstruction.” References from selected papers were reviewed for relevance and used for information-gathering as well. Ureteral obstruction most commonly occurs on the right side, due to ileal involvement. Clinical diagnosis is difficult, as symptoms are notably not genitourinary in origin;rather they are more musculoskeletal in nature. Treatment centers on disease control and temporary drainage of the affected kidney. Though rare, hydronephrosis and ureteral obstruction may develop as a result of inflammatory bowel disease. Due to atypical presenting symptoms, a high clinical suspicion is needed to affirm the diagnosis and ensure proper treatment.展开更多

This condition is not so rare in our setting. We herein, reported two cases of giant hydronephrosis, seen in two young patients respectively with 5 and 9 years old and their collecting system containing 4000 ml and 5000 ml of urines respectively. Only simple nephrectomy was performed for the two cases with renal function impairment and the post operative course was uneventful. Our purpose through these cases reports is to discuss diagnosis features and management of such condition in our setting, a context of low income countries as Burkina-Faso where diagnosis tool and further investigation are not always available.展开更多

The frequency of the items, the etiologies and the different treatments carried out were elucidated. The patients were all females. The hydronephrosis affected the left kidney. The most frequent etiology was pyelouretral junction syndrome seconded by obstructive nephrolithiasis in the upper urinary tract. One of the last etiologies was lower pole vascular plexus. Three nephrectomies and one K?SS-HEYNES-ANDERSON pyeloplasty were carried out. Conclusion: Giant hydronephrosis is a rare condition. The etiologies were organic-based and malformed. The therapeutic attitude adopted shows the interest of an antenatal diagnosis for early care.展开更多
