Assessment of Cases of Congenital Obstructive Uropathy in Children

Background: The aim is to assess cases of congenital obstructive uropathy in children.Material & Methods:Sixty- five children in age ranged 5-12 years of either gender with congenital obstructive uropathy were recruited for the study. In all cases, ultrasonography was done in all cases. Growth of the child was monitored and height standard deviation score (Ht-SDS) was calculated annually. Glomerular filtration rate (ml/min/1.73 m2) was calculated.Results:Out of 65 patients, males were 40 and females were 25. Etiology found to be ureteropelvic junction obstruction (PUJO) in 12, posterior urethral valve (PUV) in 14, PUJO + PUV in 30 and obstructive megaureter in 9 cases. Symptoms were fever in 34, pain abdomen in 20, burning micturition in 45, poor urinary stream in 21 and flank pain in 15 cases. Treatment given was pyeloplasty in 14, nephrectomy in 20, PUV fulguration in 11, ureterocele decompression in 12 and ureteric reimplantation in 8 cases.Conclusions:Most common etiologies for congenital obstructive uropathy in children were congenital uretero-pelvic junction obstruction and posterior urethral valve. Male preponderance was seen with burning micturition.

Surviving complications of retroperitoneal fibrosis with intermittent relapses over a period of 20 years: case report and literature review / Sobrevivir a las complicaciones de la fibrosis retroperitoneal con recaídas intermitentes durante un período de 20 años: reporte de un caso y revisión de la literatura

Idiopathic retroperitoneal fibrosis is a rare fibro-inflammatory disease of varied etiology which usually originates around aorta and spreads caudally along Iliac vessels into adjacent retroperitoneum causing ureteral obstruction as the most frequent complication.A 53-year-old male patient presented with complaint of mild pain in both the legs off and on. On investigating further, we found that he had been struggling with intermittent relapses every 3-4 years for last 20 years since he was first diagnosed with Idiopathic Retroperitoneal Fibrosis. He was 33-year-old when he first developed the symptoms of anuria for 48 hours and was diagnosed with Idiopathic retroperitoneal fibrosis. This was followed by atrophy of left kidney and hypertension 6 years later, then hypothyroidism after another 3years and finally involvement of Inferior Vena Cava and acute Deep Vein Thrombosis of lower limbs after another 3-4 years. His deep vein thrombosis was well managed in time. He was put on glucocorticoids everytime he had a relapse and a complication.We did a review of literature to understand recent advances about its pathogenesis, diagnosis, investigations and management. We searched in PubMed using terms like retroperitoneal fibrosis alone and in combination with related terms such as Inferior Vena Cava thrombosis, Deep Vein Thrombosis, Tamoxifen, Methotrexate. This case is unique as it is very rare to find acute Deep Vein Thrombosis in Idiopathic retroperitoneal fibrosis without development of any collaterals when Inferior Vena Cava lumen is compromised to almost complete obstruction.After a follow up of 20 years patient is doing well in terms of physical activity and psychological wellbeing with anti-hypertensives, thyroxine and anti-coagulants. Is the disease-free interval actually free of the disease or it just subsided with immunosuppressants to become active after some time?

La fibrosis retroperitoneal idiopática es una enfermedad fibroinflamatoria rara, de etiología variada que generalmente se origina alrededor de la aorta y se propaga caudalmente a lo largo de los vasos ilíacos en retroperitoneo adyacente causando obstrucción ureteral como la complicación más frecuente.Reportamos el caso de un paciente varón de 53 años que se presentó con un dolor leve en ambas piernas. Al investigar más a fondo, descubrimos que había estado luchando con recaídas intermitentes cada 3-4 años durante los últimos 20 años desde que se le diagnosticó por primera vez fibrosis retroperitoneal idiopática. Tenía 33 años cuando desarrolló por primera vez los síntomas de anuria durante 48 horas y se le diagnosticó fibrosis retroperitoneal idiopática. Esto fue seguido por atrofia del riñón izquierdo e hipertensión 6 años después, luego hipotiroidismo después de otros 3 años y finalmente afectación de la vena cava inferior y trombosis venosa profunda aguda de las extremidades inferiores después de otros 3-4 años. Su trombosis venosa profunda se controló bien a tiempo. Le recetaron glucocorticoides cada vez que tenía una recaída y una complicación.Hicimos una revisión de la literatura para comprender los avances recientes sobre su patogenia, diagnóstico, investigaciones y manejo. Se realizaron búsquedas en PubMed utilizando términos como fibrosis retroperitoneal sola y en combinación con términos relacionados como trombosis de la vena cava inferior, trombosis venosa profunda, tamoxifeno, metotrexato. Este caso es único, ya que es muy raro encontrar trombosis venosa profunda aguda en fibrosis retroperitoneal idiopática sin desarrollo de colaterales cuando la luz de la vena cava inferior está comprometida hasta una obstrucción casi completa.Después de un seguimiento de 20 años, el paciente se encuentra bien en términos de actividad física y bienestar psicológico con antihipertensivos, tiroxina y anticoagulantes. ¿El intervalo libre de enfermedad está realmente libre de la enfermedad o simplemente disminuyó con inmunosupresores para activarse después de algún tiempo?

Non-endoscopic management of a giant ureterocele: a case report in resource poor African hospital

Ureterocele is a cystic dilatation of the distal sub mucosal part of the ureter. It is a congenital anomaly that may co-exist with other anomalies. It has an incidence 1 in 4000 live births. Patients present with symptoms at paediatric age or may remain asymptomatic till adulthood.  Our 30 year old female patient was assessed for a giant orthotropic right ureterocele with obstructive uropathy, in a hospital that has no modern facilities for endoscopic treatment. She then had successful open surgical repair of the ureterocele with satisfactory outcome. Minimally invasive endoscopic treatment options remains the gold standard.  Patients from poor resource regions can as well be treated successfully by open surgical repair like our index case presented.

Obstructive uropathy complicating eosinophilic cystitis

@#Eosinophilic cystitis is a rare clinicopathologic condition characterized by predominance of eosinophils throughout the bladder wall. The exact disease mechanism is still being debated. However, it is highly associated with atopy and other immunologic conditions. Reported here is a case of eosinophilic cystitis that presented with irritative voiding symptoms with right-sided flank pain, peripheral eosinophilia, and unilateral obstructive uropathy on imaging. Diagnosis was confirmed and documented with cystoscopy and bladder biopsy. Obstructive uropathy was managed with urinary diversion using double J stent. Immunologic signs and symptoms were treated with corticosteroid and antihistamine. Additionally, irritative voiding complaint was managed with antimuscarinic drug. Patient’s condition is now on remission with normal eosinophil count and creatinine levels, and normal urinalysis. Resolution of obstructive uropathy and bladder pathology were noted on follow up imaging and cystoscopy, respectively.

Obstructive Acute Kidney Injury with Maintenance of Diuresis: A Case of Ureter Bifidity / Lesión Renal Aguda Obstructiva con Mantenimiento de la Diuresis: Un Caso de BifidezUreteral

Abstract Percutaneous kidney biopsyin transplanted kidneys remains an essential and commonly performed procedure required for diagnostic and prognostic information. Hemorrhage is the main complication of renal graft biopsy. We report a case of a 47-year-old caucasian womanadmitted to perform an ultrasound(US)-guided biopsy of the renal graft. Six hours later, she presented with macroscopic hematuriawhichimproved after urethral catheterization and intravenous hydration. However the hematuria reappeared associated with anemia and worsening of the serum creatinine value. The US study, revealed hydronephrosis with high Doppler derived renal resistive index compatible with clot obstruction.Despite the vesical lavage with drainage of several clots, the patient rapidly progressed to hemorrhagic shock with worsening of renal function. Pelvic computed tomography (CT) revealed calyx and pelvis duplicity and ureter bifidity which merged into a single ureter and inserted into the right anterolateral wall of the bladder. The inferior ureter was enlarged due to an obstructive clot. Most acute obstructive uropathies are associated with significant pain or the abrupt diminution of urine flow. The presence of ureter bifidity in the CT study explained the maintenance of significantdiuresis despite obstruction, located only to the lower ureter but with sufficient functional impact to condition acute kidney injury (AKI).

Resumen La biopsia renal percutánea en riñones trasplantados sigue siendo un procedimiento esencial y común, necesario para obtener información diagnóstica y pronóstica. La hemorragia es la principal complicación de la biopsia de injerto renal. Presentamos un caso de una mujer caucásica de 47 años, quien fue hospitalizada para la realización de una biopsia de injerto renal guiada por ultrasonido (US). Seis horas después, presentó hematuria macroscópica que mejoró después de la cateterización uretral e hidratación intravenosa. Sin embargo, la hematuria reapareció asociada con anemia y empeoramiento del valor sérico de creatinina. El estudio de US reveló, mediante Doppler, una hidronefrosis con alto índice de resistencia renal, compatible con obstrucción por un coágulo. A pesar del lavado vesical con drenaje de varios coágulos, la paciente progresó rápidamente a choque hemorrágico con empeoramiento de la función renal. La tomografía computarizada (TC) pélvica reveló la duplicidad del cáliz y la pelvis y la bifidez ureteral, que se fusionó en un solo uréter y se insertó en la pared anterolateral derecha de la vejiga. El uréter inferior se agrandó debido a un coágulo obstructivo. La mayoría de las uropatías obstructivas agudas están asociadas con dolor significativo o la disminución abrupta del flujo de orina. La presencia de la bifidez del uréter en el estudio de TC explicó el mantenimiento de una diuresis significativa a pesar de la obstrucción, localizada solo en el uréter inferior, pero con suficiente impacto funcional como para provocar insuficiencia renal aguda (IRA).

Obliterative le fort’s colpocleisis for acute kidney injury caused by pelvic organ prolapse in elderly woman

Pelvic organ prolapse (POP) is the descent of pelvic organs through the vagina, which sometimes causes hydronephrosis. Here authors report a case of an eighty five year old woman with a fourth degree uterine prolapse with obstructive uropathy. She was treated with a conservative surgery Le Fort’s colpocleisis. Following which the patient’s renal functions and symptoms improved. Hence authors conclude that colpocleisis can be considered as the option for elderly women who have completed the family with no desire to preserve the sexual function especially in women with co morbities where pelvic reconstructive surgeries pose a challenge.

Bladder endometriosis presenting as obstructive uropathy in a post-hysterectomy patient

@#Urinary tract endometriosis is present in approximately 1% of women. Bladder endometriosis (BE) is defined as presence of endometrial glands and stroma in the detrusor muscle. Close collaboration of the urologists and gynecologists in dealing with urinary tract endometriosis is necessary in order to establish both the correct diagnostic procedure and the most adequate management. Presented here is the case of a 42-year old female, G3P3 (3003), who presented with intermittent episodes of right-sided flank pain four months post-hysterectomy. She was initially diagnosed to have a bladder tumor and underwent transurethral resection of bladder tumor. Histopathological examination of the resected specimen revealed endometriosis.

Variación de la microglobulina beta-2 en orina fetal en punciones sucesivas previo a derivación vesicoamniótica antenatal

Introduction. Fetal obstructive uropathy can be treated early in pregnancy by intrauterine vesicoamniotic shunting, immediately after diagnosis by ultrasound, in specific cases with a favorable prognosis in renal function using fetal urine beta2 microglobulin. Objective: To determine the changes of beta-2 microglobulin in consecutive samples of fetal urine in 48 - 72 hour-intervals in fetuses with obstructive uropathy at 16 weeks of gestation. Methods: We designed a descriptive and longitudinal study, including 15 pregnant women whose fetuses were diagnosed with obstructive uropathy without chromosomal abnormalities, performing vesicocentesis for urinary biometry. Results: Beta-2 microglobulin values were higher than 4 mg/dL in the first vesicocentesis of all 15 cases and decreased to less than 4 mg/dL in 7 cases (46.6%) after the second vesicocentesis. In all cases when beta-2 microglobulin was less than 8 mg/dL in the first vesicocentesis, there was a decrease to nearly 4 mg/dL (maximum 4.3 mg/dL) in the second vesicocentesis. Conclusions: Vesicoamniotic shunting should be performed in all cases of fetal obstructive uropathy when the values of beta-2 microglobulin are less than 8 mg/dL in the first vesicocentesis.

Antecedentes y objetivos. La uropatía obstructiva fetal puede ser tratada precozmente mediante la colocación de derivación vesicoamniótica intrauterina. Los criterios de tratamiento incluyen la ausencia de malformaciones mayores asociadas, cariotipo normal y función renal conservada demostrada por microglobulina beta-2 4 mg/dL en los 15 casos con la primera vesicocentesis, y disminuyeron a < 4 mg/dL en 7 casos (46,6%) en la segunda vesicocentesis. En todos los casos cuando la microglobulina beta-2 fue < 8 mg/dL en la primera vesicopunción, siempre disminuyó a valores muy próximos a 4 mg/dL (máximo de 4,3 mg/dL) en la segunda vesicopunción. Conclusiones. Se plantea la colocación in útero de derivaciones vesicoamnióticas en los casos de uropatía obstructiva fetal cuando la microglobulina beta-2 sea < 8 mg/dL en la primera vesicopunción, omitiendo realizar una segunda vesicopunción.

A study of Obstructive Uropathy among Children.

Background: Where in the infection occur repeatedly leaving residual inflammatory changes. It is more common in the presence of structural or functional anomalies of the urinary tract, which interfere with drainage of urine. Common organisms are E. coli in early infancy, while the later resistant organism like proteus and klebsiella predominate. Objective: To study, obstructive uropathy among children. Methods: A hospital-based study was carried out among children of 6 months to 5 years of age who satisfied inclusion and exclusion criteria. Complete detailed history, examination and investigations like urine for culture and sensitivity, and radiological investigations were carried out. Results: Out of total no. of 60 cases sent for urine culture, 44 cases were culture positive. E. coli is isolated in 32 cases (53.3%). Klebsiella in 7 cases (11.6%) and pseudomonas in only 3 cases (5%) and proteus in 2 cases (3.3%). Out of total no of cases, 60 cases, 15 cases were presented with predisposing factors like vesical stones in 8 cases (13.3) noted on plain X-ray of abdomen, where as hydronephrotic changes were seen in 7 cases (11.6%). Conclusion: Organism isolated in present study E. coli (53.3%) was commonest organism isolated, then followed, by Klebsiella, Pseudomonas and Proteus.

The Renal Ultrasound in Patients with Acute Kidney Injury.

Aims: Acute Kidney Injury (AKI) is seen in 15% of hospitalized patients and a renal ultrasound (RUS) is often ordered to exclude an obstructive cause in the initial evaluation of AKI. This study was done to evaluate the usefulness of a RUS in patients with AKI in a developing country. Methods: This was a retrospective study on all patients who were referred to nephrology with AKI and had a RUS, over a one-year period at a tertiary care teaching hospital of Karachi, Pakistan. The patients’ charts were reviewed for clinical characteristics and the RUS findings were documented. Results: A significant number of patients did not have documented risk factors for obstruction based on the medical history. Hydronephrosis was found in 22.5% (25 out of 111) of patients, and in 14 of these cases, the etiology of the acute kidney injury was found to be obstructive uropathy. The presence of nephrolithiasis and/or benign prostatic hypertrophy was associated with and increased likelihood of finding hydronephrosis on RUS. Conclusions: We thus recommend doing a renal ultrasound in all cases of AKI due to the fact that most of the time in a developing country, an accurate history is not available, and the prevalence of stone disease and obstructive uropathy is high.

Atualização da abordagem de infecção do trato urinário na infância / Update on the approach of urinary tract infection in childhood

Resumo Objetivo: A infecção do trato urinário (ITU) é a infecção bacteriana mais comum na infância. A ITU pode ser o evento sentinela para alteração renal subjacente. Ainda há muitas controvérsias com relação ao tratamento adequado da ITU. Neste artigo de revisão, discutimos as últimas recomendações para diagnóstico, tratamento, profilaxia e imagiologia da ITU na infância, com base em comprovação e, na sua ausência, no consenso de especialistas. Fonte de dados: Os dados foram coletados após uma revisão da literatura e pesquisa no Pubmed, Embase, Scopus e Scielo. Resumo dos dados: No primeiro ano de vida, as ITUs são mais comuns em meninos (3,7%) do que em meninas (2%). Os sinais e sintomas da ITU são muito inespecíficos, principalmente em neonatos e durante a infância. A febre é o único sintoma em muitos casos. Conclusões: O histórico clínico e exame físico podem sugerir ITU, porém a confirmação deve ser feita por urocultura. Antes da administração de qualquer agente antimicrobiano, deve ser feita coleta de urina. Durante a infância, a coleta de urina adequada é essencial para evitar resultados falso-positivos. O diagnóstico e o início do tratamento imediatos são importantes na prevenção de cicatriz renal de longo prazo. Neonatos febris com ITUs devem ser submetidos a ultrassonografia renal e da bexiga, Agentes antibacterianos intravenosos são recomendados para neonatos e neonatos jovens. Recomendamos também a exclusão de uropatias obstrutivas o mais rapidamente possível e posterior refluxo vesico-ureteral, caso indicado. A profilaxia deve ser considerada em casos de elevada susceptibilidade a ITU e risco elevado de danos renais.

Abstract Objective: Urinary tract infection (UTI) is the most common bacterial infection in childhood. UTI may be the sentinel event for underlying renal abnormality. There are still many controversies regarding proper management of UTI. In this review article, the authors discuss recent recommendations for the diagnosis, treatment, prophylaxis, and imaging of UTI in childhood based on evidence, and when this is lacking, based on expert consensus. Sources: Data were obtained after a review of the literature and a search of Pubmed, Embase, Scopus, and Scielo. Summary of the findings: In the first year of life, UTIs are more common in boys (3.7%) than in girls (2%). Signs and symptoms of UTI are very nonspecific, especially in neonates and during childhood; in many cases, fever is the only symptom. Conclusions: Clinical history and physical examination may suggest UTI, but confirmation should be made by urine culture, which must be performed before any antimicrobial agent is given. During childhood, the proper collection of urine is essential to avoid false-positive results. Prompt diagnosis and initiation of treatment is important to prevent long-term renal scarring. Febrile infants with UTIs should undergo renal and bladder ultrasonography. Intravenous antibacterial agents are recommended for neonates and young infants. The authors also advise exclusion of obstructive uropathies as soon as possible and later vesicoureteral reflux, if indicated. Prophylaxis should be considered for cases of high susceptibility to UTI and high risk of renal damage.

The Significance of Abnormal Urine Stream in the Male Infant: A Survey of Mothers’ Knowledge in a South-East Nigerian City and Implications for Preventive Nephrology.

Introduction/Aim: Chronic kidney disease (CKD) in children is now a global health problem, and obstructive uropathy plays a major causative role. Reports however indicate limited CKD knowledge and awareness among caregivers which may be a draw-back in ‘preventive nephrology’. The study aims to determine the knowledge of mothers regarding the significance of abnormal urine stream in the male newborn infant. Study Design: Paediatric Nephrology Clinic, University of Nigeria Teaching Hospital (UNTH), Ituku-Ozalla, Enugu, South-East Nigeria. Period of six months (June to December, 2013). Place and Duration: Paediatric Nephrology Clinic, University of Nigeria Teaching Hospital (UNTH), Ituku-Ozalla, Enugu, south-east Nigeria. Period of six months (June to December, 2013). Methodology: A cross-sectional, descriptive study of 204 mothers who met the study criteria was conducted using interviewer-administered, structured questionnaires. Their knowledge on whether abnormal stream suggests disease was measured on a rating scale of 1=never, 2=sometimes to 3=always. Data were analyzed with appropriate descriptive statistics on SPSS (version 13.0). P value <0.05 was chosen as level of statistical significance. Results: Eighty eight (43.1%) of the mothers had a knowledge scale of 3, while 70 (34.3%) had a scale of 2. There was no statistically significant difference between the social classes of the two groups of mothers (P=.25). Conclusion: The over-all knowledge of mothers is adjudged as modest and is not influenced by socio-economic status. Preventive intervention strategies should include health education to promote early self-referral and diagnosis.

Comparison of compliance and response rate of radiotherapy alone vs. chemo radiotherapy in stage IIIB carcinoma cervix patients having obstructive uropathy.

Background: Carcinoma cervix is the second most common malignancy among females of India (1). The low incidence rate in developed countries is because of well-developed screening programs and awareness among women. But in developing countries like India, because of lack of health awareness and lack of proper screening facilities, patients usually present in advanced stages. They also have a lot of associated co-morbidities like obstructive uropathy with or without deranged RFT, anaemia, poor nutrition, tuberculosis, diabetes, hypertension, multiple genital infections etc. The standard treatment of advanced carcinoma cervix is radiotherapy with weekly cisplatin as radio-sensitizer but it has been observed that a lot of patients are not able to tolerate toxic side effects of concurrent chemo radiotherapy. Methods: We have chosen only one co-morbid condition i.e. obstructive uropathy with or without deranged RFT because of small sample size. So the aim of this study was to compare the compliance and response rate of concurrent chemo radiotherapy versus radiotherapy alone in patients of locally advanced carcinoma cervix having obstructive uropathy with or without deranged RFT. Results: Only 36% (n=9) patients in the RT+CT group received the complete planned five cycles of weekly cisplatin. Average number of cycles of cisplatin missed in the chemo-radiotherapy group was one (range 0-3). Compliance was better in the RT alone group. The average time in the RT alone group to complete radiotherapy was 57.72 days and in RT+CT group was 60.72 days. In the RT alone group the treatment time was prolonged by an average of 1.72 days (range 3-6) while in the CT+RT group it was prolonged by 4.72 days (range 2-14). Conclusions: It is hereby concluded that radiotherapy alone for locally advanced squamous cell cervical carcinoma patients having associated co morbid conditions like deranged RFT had a better compliance then with the concurrent chemoradiotherapy regime.

Review of genitourinary tuberculosis with focus on end-stage renal disease / Revisão acerca da tuberculose genitourinária com foco na insuficiência renal crônica terminal

Tuberculosis (TB) is a current public health problem, remaining the most common worldwide cause of mortality from infectious disease. Recent studies indicate that genitourinary TB is the third most common form of extra-pulmonary disease. The diagnosis of renal TB can be hypothesized in a non-specific bacterial cystitis associated with a therapeutic failure or a urinalysis with a persistent leukocyturia in the absence of bacteriuria. We report on the case of a 33-year-old man who presented on admission end stage renal disease (ESRD) secondary to renal TB and a past history of pulmonary TB with important radiologic findings. The diagnosis was based on clinical findings despite all cultures being negative. Empiric treatment with tuberculostatic drugs was started and the patient became stable. He was discharged with no symptom, but without renal function recovery. He is on maintenance hemodialysis three times a week. TB is an important cause of kidney disease and can lead to irreversible renal function loss.

A tuberculose (TB) é um problema atual de saúde pública, persistindo como a causa mais comum de óbito por doenças infecciosas. Estudos recentes indicam que a TB genitourinária é a terceira forma mais comum de doença extra-pulmonar. O diagnóstico da TB renal pode ser suspeito na presença de cistite bacteriana não-específica associada a falha terapêutica ou com exame de urina apresentando leucocitúria persistente na ausência de bacteriúria. Relatamos o caso de um paciente de 33 anos, sexo masculino, que apresentou na admissão insuficiência renal crônica terminal secundária à TB renal, que tinha história prévia de TB pulmonar, com importantes achados radiológicos. O diagnóstico foi baseado nos achados clínicos apesar de todas as culturas terem sido negativas. Tratamento empírico com drogas tuberculostáticas foi iniciado e o paciente evoluiu estável. Foi de alta assintomático, mas sem recuperação da função renal. Ele encontra-se em hemodiálise três vezes por semana. A TB é uma causa importante de doença renal e pode levar à perda irreversível da função renal.

An Overview of Renal Diseases in Children in Pokhara.

Objective: To determine the current pattern and prevalence of renal diseases in childhood in this region of Nepal. Material and Methods: A retrospective study of the renal diseases in children attending the Pediatric OPD and those hospitalised in Manipal Teaching Hospital, Pokhara was done over a period of 6 years (September 2000- September 2006). A detailed clinical and laboratory evaluation was performed at baseline. The children were managed according to disease diagnosed. These cases are under follow up and some have undergone surgical treatment. Results: 228 children (123 boys & 105girls) were diagnosed to have renal disease. Among them 39.5% had urinary tract infection (UTI), 30.7 % were suffering from acute glomerulonephritis (AGN), 17.5% were cases of nephrotic syndrome (NS) and 12 % had some other problems for example, 6.14% had genetic defects, 2.63% had renal Stone, 2.2% had pre-renal acute renal failure, unexplained recurrent hematuria in 1.3%. All the cases of UTI underwent through investigation and were treated accordingly. All cases of AGN are planned for follow up for 1½ yrs and among them 3 required biopsy till date. All cases of NS are under regular follow-ups and 2 have undergone biopsy. Renal stone was operated successfully. All cases of acute and chronic renal failures had required dialysis. Out of 5 (2.5%) chronic renal failures, 2 with end stage renal disease expired after repeated hemodialysis and three are still requiring dialysis. Among the obstructive uropathies, 43 % had renal stone, 36 % had posterior urethral valve and 21% VUR. Conclusion: It can be concluded that renal disease is not uncommon in children. It can be completely cured with proper and adequate treatment. Sometimes it has a bad prognosis when it reaches end stage renal disease. Early recognition, timely treatment and regular follow up are mandatory in management of children with renal diseases.

In Utero Shunting for Fetal Hydrothorax, Ascites and Obstructive Uropathy: A Review of 7 Cases / 대한주산의학회잡지

OBJECTIVE: To evaluate the value of intrauterine shunting and to investigate the complication and outcome of these procedures for different fetal indications. METHODS: 7 fetuses who underwent 13 intrauterine catheter shunting from 1992 to 1997 were reviwed. The indications were uni-or bilateral hydrothorax in 4 cases, ascites in one case, and obstructive uropathy in 2 cases. RESULTS: Catheter migration occurred 6 times out of the 13 shunts (46%). Procedure related death rate was 23% (3/13); within 48 hours of pleuroamniotic shunting, amniorrhexis and coincidental abruptio placenta resulting in one fetal death and each one of amniorrhexis and premature labor resulting in 2 neonatal deaths. Pregnancy was terminated after shunting in one case of urethral atresia. Postnatal survival rate was 50% (3/6). CONCLUSION: A high complication rate requires the selection of cases for shunting. A large prospective controlled trial is needed to determine its value.
