“…Serology is used erratically in the diagnosis of patients with cUGS-related manifestations. In several reports [ n = 7], patients underwent invasive procedures and were also found to have a positive serology for S. haematobium [ 85 , 91 , 92 , 105 , 137 , 139 , 149 ]. On the contrary, in several reports [ n = 11], eggs were not present in the urine of patients with chronic schistosomiasis [ 92 , 98 , 100 , 102 , 103 , 106 , 126 , 134 , 137 , 139 , 140 ].…”

Background Currently, there are no standardized guidelines for the diagnosis or management of the complications of urogenital schistosomiasis (UGS). This systematic review of the literature aims to investigate the state of the art in reference to diagnostic approaches and the clinical management of this condition. Methods A systematic review of literature published between January 1990 and January 2021 was conducted in the MEDLINE database, scoping for articles regarding diagnostic means or therapeutic options for the complications of UGS, namely obstructive uropathy, bladder cancer, abortion, ectopic pregnancy, infertility, kidney failure, urolithiasis and the need for invasive procedures. Relevant data were then extracted from the articles deemed eligible according to the inclusion criteria. Main results In total, 3052 articles were identified by the research query, of which 167 articles fulfilling inclusion criteria after title/abstract screening and full-text evaluation were included, 35% on both diagnostic and therapeutic aspects, and 51% on diagnosis and 14% on therapy. Ultrasound was the most frequently tool employed for the diagnosis of UGS complications showing a good performance. Concerning the management of hydronephrosis, the majority of available evidences came from community-based studies where universal treatment with praziquantel was used leading to decrease of prevalence of obstructive uropathy. Concerning studies on surgical procedures, laser endoureterotomy followed by stenting was mostly employed in adult patients leading to a crude cure rate of 60% (43 of 71 patients). In the case of severe hydronephrosis, surgery consisting of ureteral re-implantation showed excellent results with a crude cure rate of 98% (157 cured patients of 160 treated). Concerning bladder cancer, data on 93 patients with a clear diagnosis of UGS-related bladder were available reporting a variable and sometime combined approach based on disease stage. Available data on diagnosis and management of abortion, ectopic pregnancy, infertility, kidney failure, urolithiasis and the need for invasive procedures due to UGS are also presented. Conclusions The review produced a complete picture of the diagnostic and therapeutic options currently available for complicated UGS. These results can be useful both for guiding clinicians towards correct management and for tracing the direction of future research.

“…A definitive diagnosis of schistosomiasis requires histopathology, which reveals the characteristic S. haematobium eggs with their terminal spines and granulomas. The current understanding is that S. haematobium is the cause of GU schistosomiasis, while other Schistosoma species cause intestinal schistosomiasis[ 1 , 9 , 11 , 12 ]. However, our patient showed the presence of eggs with a lateral spine with GU schistosomiasis, which could indicate the possibility of an infection with another Schistosoma species.…”

BACKGROUND Genitourinary (GU) schistosomiasis is a chronic infection caused by a parasitic trematode, with Schistosoma haematobium ( S. haematobium ) being the prevalent species. The disease has a variable prevalence around the world, with a greater burden on, but not limited to Africa, South America, Asia, and the Middle East. CASE SUMMARY We report the case of a 30-year-old man who presented with symptoms of bladder stones. During endoscopic cystolithalopaxy, we did not detect any stones in the bladder. Upon careful scanning of the urinary bladder trigone, sandy patches were detected. We performed endoscopic resection, which revealed a closed diverticulum with bladder stones. The diverticular wall was sent for histopathology and revealed features of chronic granulomatous inflammation with numerous embedded Schistosoma eggs, with some of the eggs having lateral spines. The patient was treated with praziquantel, and his symptoms completely resolved. CONCLUSION GU schistosomiasis is primarily caused by S. haematobium . However, Schistosoma mansoni mediated GU schistosomiasis is unusual, making this a quite interesting case.

“… 2 Schistosomiasis is not endemic in Korea and therefore, only the imported cases have been reported in travelers to endemic areas of schistosomiasis. 3 The strategy for schistosomiasis control aims to prevent morbidity in later life through regular treatment with praziquantel, which is currently the only recommended drug for curing schistosome infections. 4 5 A number of international agencies, notably the United Nations International Children's Fund and the World Health Organization (WHO), 6 along with for-profit and non-profit organizations, supply praziquantel in bulk to developing countries.…”

Parasitological Observation in Schoolchildren with Urogenital Schistosomiasis Following Treatment with Three Different Brands of Praziquantel

This study compared the anthelminthic effects of three different brands of praziquantel being used in Sudan against Schistosoma haematobium ( S. haematobium ) infection. We enrolled 1,286 schoolchildren from six primary schools and examined their urine samples for eggs of S. haematobium at the baseline survey and follow-up two weeks after administering the medication. The schoolchildren were divided into three groups based on the three brands of praziquantel (different material production), with two school children for one brand. The overall baseline prevalence of S. haematobium infection was 15.5%. Two weeks after treatment with brands A, B, and C of praziquantel, cure rates were 87.1%, 82.4% and 83.8% respectively, and the egg-reduction rates were 69.0%, 81.0% and 70.6% respectively. There was no statistically significant difference in cure rates and egg-reduction rates between the three brands. We conclude that the three different commercial brands of praziquantel used in Sudan have similar anthelminthic effects on S. haematobium .
