Ultrasonographical aspects of urinary schistosomiasis: Assessment of morphological lesions in the upper and lower urinary tract
1986
Ultrasonographic evaluation of 213 patients with urinary schistosomiasis in different age groups was performed in an endemic area of the Democratic Republic of Congo. The results were compared with 94 age matched controls without urinary schistosomiasis. In patients the bladder showed thickening of the wall, polypoid lesions of the mucosa and bladder wall, calcifications and urinary retention. Urinary tract obstruction, predominantly unilateral, was demonstrated. The lesions increased in severity with the intensity of infection, parallel to an increase in ova excretion. Children aged between 8 and 19 years were most severely affected. Pathological lesions of the upper urinary tract were rar…
Report of results obtained in 2,934 women using donor sperm: donor insemination versus in vitro fertilization according to indication.
2011
Objective To demonstrate that the use of donor sperm leads to varying outcome rates and that its use has evolved. Design Retrospective observational cohort study. Setting University-affiliated private IVF setting. Patient(s) Women (2,934) undergoing donor insemination (DI) or IVF with donor sperm (IVF-D). Intervention(s) None. Main Outcome Measurement(s) We evaluated the distribution of the clinical indications for the use of donated sperm, studying the reproductive outcome. Result(s) A total of 1,663 DI (57%) and 1,271 IVF-D (43%) were performed. There were significant differences in the indications for the use of donated sperm (DI vs. IVF-D). Regarding pregnancy rates (PR), cases of nonob…
Outcome of intracytoplasmic sperm injection with and without polar body diagnosis of oocytes.
2008
Objective To compare the reproductive outcome of women undergoing intracytoplasmic sperm injection (ICSI) with or without polar body diagnosis of oocytes. Design Nonrandomized retrospective study. Setting University-based human genetic institute in collaboration with a private fertility center. Patient(s) Six hundred seven women undergoing ICSI with polar body diagnosis and 591 women undergoing ICSI without polar body diagnosis at the same time in the same fertility center. Intervention(s) Polar body testing of ICSI oocytes by five-color fluorescence in situ hybridization. Main Outcome Measure(s) Pregnancy rate (positive fetal heartbeats) and live-birth rate (of at least one child). Result(…
Colonic Conduit in Children
1996
Complication rates of up to 86.6% have been reported after creation of an ileal conduit. In contrast to others, we construct an antirefluxing isoperistaltic colonic for incontinent diversion in children.Between 1968 and 1989 a colonic conduit was created in 105 patients up to age 20 years for neurogenic bladder (76), bladder exstrophy (16) and other reasons (13). Long-term followup (minimum 5 years, mean 16.3 years, range 5 to 26) was possible in 84 patients (159 renal units).Early and late stenosis at the ureterocolic anastomosis, and stomal stenosis occurred in 7.6 and 15.5% of the cases, respectively. Renal calculi developed in 8.2% of the renal units. Eight kidneys without function afte…
Simplified Orthotopic Ileocecal Pouch (Mainz Pouch) for Bladder Substitution
2003
Objective To report operative modifications that render construction of the orthotopic Mainz pouch more simple, namely formation of the pouch using absorbable staples and utilization of the ileocecal valve as an antireflux mechanism. Patients and methods Between January 2001 and May 2002 out of 92 cystectomy cases, 21 patients (20 males and 1 female) underwent a simplified orthotopic Mainz pouch. The ureters were implanted via Wallace or Nesbit technique in the supravalvular portion of the ileocecal valve. The mean (range) age was 58 (43 - 74) years and the mean follow-up is 11.6 months (range 1 - 27). Results No staple-related complications were encountered. Four renal units (8.8 %) were d…
The Mainz Pouch II
1994
The Mainz pouch II procedure has proved to be a substantial modification of the classical technique of ureterosigmoidostomy at many institutions. To date we have used this procedure in 72 patients, including 15 children. Detubularization causes a low pressure and eliminates high-pressure contractions. Without the risk of compromising the blood supply the pouch is fixed at the promontory which reduces the risk of ureteral kinking and upper urinary tract dilatation as it is sometimes observed after ureterosigmoidostomy. The technique is not only indicated in cases of failed ureterosigmoidostomy but also for primary urinary diversion. Of the 72 patients operated, all are evaluable with a follo…
The Mainz pouch II (sigma rectum pouch).
1993
A low pressure rectosigmoid reservoir for urine is created obviating the need for colostomy, augmentation or extensive bowel surgery. Antimesenteric splitting of the intestine at the rectosigmoid junction and subsequent side-to-side anastomosis are performed. Urodynamic data demonstrate that the detubularization is effective in rendering high pressure bowel contractions ineffective. Without the risk of damaging the mesentery the pouch is fixed at the promontory, which lessens the risk of ureteral kinking and upper urinary tract dilatation. The technique is indicated not only in cases of failed ureterosigmoidostomy but also for primary urinary diversion. All 47 patients who underwent the ope…
Presentation, Management and Long-Term Outcome of Ureteropelvic Junction Obstruction in Duplex Kidneys.
2015
Ureteropelvic junction obstruction in association with a duplex collecting system is a rare but challenging upper urinary tract pathology. We report our 21-year experience with this anomaly in terms of presentation, diagnostic evaluation and management.We retrospectively identified all patients with ureteropelvic junction obstruction in a duplex collecting system between 1991 and 2012. We reviewed each case for presenting symptoms, anatomy and management. Median followup was 10.8 years (range 2 to 22).Ureteropelvic junction obstruction in duplex kidneys was diagnosed in 21 patients. Ten patients presented with clinical symptoms such as flank pain and urinary tract infection but 11 were asym…
Timing of cell division in human cleavage-stage embryos is linked with blastocyst formation and quality
2012
Noninvasive markers of embryo quality are being sought to improve IVF success. The present study aimed to discover possible associations between embryo division kinetics in the cleavage stage, the subsequent ability of human embryos to reach the blastocyst stage and the resulting blastocyst morphology. A retrospective cohort study analysed 834 embryos from 165 oocyte donation couples using a time-lapse monitoring system that allowed the recording of the exact timings for key events related to embryo development. Timing parameters were categorized into four quartiles. The probability of an embryo developing to a blastocyst was linked to a strict chronology of development. To further evaluate…
