小儿特发性膀胱结石的经皮膀胱穿刺取石术:两个发展中国家的155例经验

世界核心医学期刊文摘（儿科学分册） 2006年第4期2卷 32-32页

作者： salah m.A. Holman E. Khan A.m. Toth C. 余晓梅 Department of Urology Medical and Health Science Center University of Debrecen Debrecen 4032 Hungary

Purpose: The aim of this study was to evaluate retrospectively our experience with percutaneous cystolithotomy (PCCL) in children having endemic urinary bladder stones. methods: Between January 1993 and June 2003, 155 children younger than 14 years underwent PCCL. The patients’ age ranged from 8 months to 14 years (average, 4.5 years). One hundred fifteen patients (74.2% ) were 5 years or younger, 31 patients (20% ) were between 6 and 10 years, and 9 patients (5.8% ) were between 11 and 14 years. There were 153 boys and 2 girls. The stone size ranged from 0.7 to 4 (average, 2.3) cm. The procedure was done under general anesthesia. Dilation of the tract was made under fluoroscopy. The instrument was the adult 26F nephroscope, the same that is used for percutaneous nephrolithotomy. Ultrasound disintegration was needed for stones larger than 1 cm. Suprapubic catheter was left for 24 hours. Urethral catheter was kept for 48 hours. Results: All patients became stonefree. The average operating time was 20 (5- 60) minutes. The average hospital stay was 2.7 (2- 5) days. No any severe intra- or postoperative complication was observed. The nucleus and/or the main component of the stones were ammonium acid urate in 144 patients (93% ). Conclusions: Based on our experience, we can conclude that PCCL is a safe and effective method for treatment of endemic bladder stones in children. It reduces morbidity and hospital stay, and thus the cost of treatment. Our series proves the nutritional etiology of the endemic pediatric bladder stones.

Open Journal of Urology 2019年第1期9卷 19-29页

作者： mohemid m. Al-Jebouri Salih A. mdish Department of microbiology College of Medicine University of Tikrit Tikrit Iraq Department of Clinical Laboratory Tikrit Teaching Hospital Tikrit Iraq

Objectives: The main objective of this study was to investigate the bacterial infections of seminal fluid in males with primary infertility. The patients were referred to and/or visiting the Urology Department in salah Al-Deen Teaching Hospital. methods: The present study was carried out from may 2017 to June 2018 and the number of the patients group was 60. The patients aged between 20 to 50 years. Semen was collected from infertile men of a couple that female failed to become pregnant after one year of regular and unprotected intercourse of marriage and submitted for seminal fluid analysis for the bacteriological analyses. The control group consisted of 50 fertile male who were selected randomly from Tikrit City during the period of this study. Semen culture was done for all the patients and the control group. Results: There were 30 patients who suffered from bacteriospermia and 16 of them (53.3%) were infected with gram positive organisms, while only 14 (46.7%) patients were infected with gram negative organisms. The most common organism was Staphylococcus aureus which was isolated from bacteriospermia. Escherichia coli, Enterococcus faecalis, Klebsiella pneumoniae, S. saprophyticus, Proteus mirabilis and Niesseria gonorrhoae were also isolated and the frequencies of isolation were 23.3% (7), 13.3% (4), 10.0% (3), 10.0% (3), 6.6% (2), and 6.6% (2) respectively. The present study showed many antibiotics were not active against gram positive bacteria isolated e.g. the resistance frequenciy to rifampcin, vancomycin and clindamycin was 48%, 44% and 40% respectively. Conclusions: The gram positive organisms were more prevalent than gram negative organisms in patients with bacteriospermia and the isolationfrequencies of two groups were 16 (53.3%) and 14 (46.7%) respectively. The most effective antimicrobial agents were amikacin, ciprofloxacin and levofloxacin and the least effective one was ceftazidime, whereas moxifloxacin, norfloxacin, gentamicin, azithromycin, moxif

Objective: This study aimed to investigate the histopathological examination of the testicular biopsies in infertile males with azoospermia. The patients were referred to the Urology Department in salah Alden Hospital. methods: The present study was carried out from may 2017 until June 2018 and the number of the patients group was 60. The patients aged between 20 to 50 years. 20 of them were selected and subjected to histopathological examinations by taking biopsies from their testes. Results: The sertoli-cell-only syndrome (SCOS) was the most common positive histopathological finding comprising 35% of the cases. This was followed by testicular atrophy with 30%, while maturation arrest was 20%. The percentage of hypospermatogenesis was 10% and normal spermatogenesis was 5%. Conclusion: Among the 20 specimens examined, the sertoli-cell-only syndrome (SCOS) was the most common positive histopathological finding. The semen analysis and testicular biopsy provide valuable information about the etiology and the fertility potential of an individual.

Background.-Studies on the infectious complications postengrafment in pediatr ic stem cell transplantation patients are rare. The aim of this study was to ass ess the incidence, types, outcome and factors affecting late infections. Patient s and methods. -A single-institution retrospective analysis was done of infect ions recorded in the first year following engrafment in children who underwent a utologous stem cell transplantation for solid tumors from January 1991 to Decemb er 2000. A systematic antimicrobial chemoprophylaxis of TmP/SmX was administered . Patients who were at high risk for varicellazona virus infection received prop hylactic acyclovir. Results. -Eighty-four assessable patients were enrolled. F ifty-four patients (64%) underwent autologous peripheral blood stem cell trans plantation and 30 patients (36%) underwent bone marrow transplantation. Forty- nine episodes of infections were documented in 39 patients(46%) of whom 27 pati ents (32%) developed infections after the first 100 days post transplantation. Bacterial septicemia occurred in nine patients of whom four patients had a cathe ter-related septicemia. Twelve patients (14%) developed localized herpes zoste r infection. Local fungal infection occurred in five patients. Infection-relate d death occurred in one patient with non-documented pneumonitis. Univariable an alysis showed a correlation between the CD34+cell dose ment of infections (P =0.04). Patients who did not go into remission after transplantation where at high risk for septicemia (P =0.007)-. multivariate ana lysis showed that a history of varicella or pretransplant varicella-zona positi vity was the only significant factor for development zoster infection (P =0.01). Conclusion. -Our study shows that infections in the first year postengrafment following autologous stem cell transplantation for solid tumors have a good prog nosis and that the use of TmP/SmX should be the single systematic antimicrobial pr

We report a case of pseudotumoral pelvic actinomycosis with lumbosacral spinal involvement in a 21 year-old woman. The radiological work-up showed a pseudotumoral left ovarian lesion extended to sacral spine, which involved the fifth lumbar vertebra. Diagnosis of actinomycosis was established in histopathological examination of the tubo-ovarian mass under laparotomy. After four months of treatment with ofloxacin and rifampicin evolution was marked by improvement of general health and infection, associated to a progressive recovery of motricity of the lower limbs. Early diagnosis of pelvic actinomycosis may prevent the occurrence of rare but severe neurological complications of this disease.
