Printed on acid-free paper Springer is part of Springer Science+Business Media (www.springer.com) Foreword I The International Society of Nephrology strives to improve access to the best possible kidney care worldwide. An important step is the training of nephrologists and physicians treating patients with renal diseases. These goals form the basis of the ISN “Global Outreach” (GO) programs – to build health equality worldwide and improve kidney care and prevention strategies around the globe by making the knowledge and experience of the developed world accessible to kidney doctors and other specialists in emerging countries. Children are a particularly vulnerable population. Unacceptable delays in the recognition and treatment of (severe) renal disease due to lack of access to basic and comprehensive care often leads to preventable, acute and chronic adverse effects caused by malfunctioning kidneys. Kidney disease during infancy to adolescence due to (intrauterine) malnutrition, genetic inheritance, nephrotoxic agents or poorly treated primary diseases has devastating, often irreversible, effects on bone health, growth and intellectual development. Disparities in preventive and curative or supportive care arise from the lack of knowledgeable health care professionals, lack of (public) health care resources and lack of individual fi nancial means to initiate and support therapies that are taken for granted in more affl uent countries. To come to grips with the global challenge of rising numbers of patients with renal diseases, the ISN created the Sister Renal Center program pairing emerging and supporting (established) centers across all continents. As the chair and ardent supporter of our GO programs, I am proud to witness the involvement of dedicated pediatric nephrologists in this endeavor. This Manual is the collaborative product of one of the few and successful pedi- atric sister center pairs, the Children’s Kidney Care Center at the St. John’s Medical College Hospital in Bangalore, India, and the Nephrology Division at the Montreal Children’s Hospital in Montreal, Canada. Written in a collaborative spirit, it empha- sizes a global perspective. May it serve health care professionals, trainees, and physicians to improve the diagnosis and treatment of children with renal diseases worldwide. Paul N. Harden Professor of Nephrology Chair, International Society of Nephrology Sister Renal Program Oxford, UK v Foreword II Today, kidney issues dramatically impact global health, especially the health of children. In developing countries, millions of people – most of them children – die each year from diseases that are preventable and treatable. For many of these chil- dren, kidney problems represent a serious threat to their survival. Important examples include – but are not limited to – the delayed recognition and treatment for congenital abnormalities of the kidney and urinary tract, which are a major cause of chronic kidney disease and secondary health problems; severe fl uid and electrolyte disturbances and acute kidney injury due to diarrhea, the #2 cause of death in children worldwide; infants with low birth weight in low income groups due to malnutrition and lack of prenatal care, with an increased risk of small kid- neys, hypertension in adolescence and chronic kidney disease; HIV associated nephropathy, particularly in areas where highly active antiretroviral therapy is not accessible. A major goal of the International Pediatric Nephrology Association (IPNA) is to reach physicians throughout the world through educational and fellowship programs and enable them to care for children with kidney diseases. This Manual of Pediatric Nephrology is designed to give pediatrician and general physicians as well as train- ees and other health care professionals a quick and practical approach to the diag- nosis and treatment of children with different types of kidney diseases. The well-structured text is easy to read and covers all important areas in the fi eld. On behalf of IPNA, I welcome this new manual as a valuable resource for prac- titioners and trainees in (pediatric) nephrology alike. Its appeal lies in the combined perspective provided by experienced nephrologists from different continents that takes into account the realities in emerging countries. It corresponds well to IPNA’s goals to “work to disseminate knowledge about kidney disease in children in the areas where care is needed most”. Isidro B, Salusky, M.D. Secretary General IPNA Distinguished Professor of Pediatrics David Geffen School of Medicine at UCLA Los Angeles, CA, USA vii Preface This manual does not want to replace standard textbooks of nephrology or pediatric nephrology. Rather, it offers a fi rst, quick and practical approach for the care of children with kidney disease. It is meant to serve practitioners, trainees, pediatri- cians, general physicians, and other health care professionals. The manual is the product of a long-lasting collaboration between two pediatric nephrology units, the Children’s Kidney Care Center at the Saint John’s Medical College Hospital (St-John’s) in Bangalore, India, and the Division of Nephrology at the Montreal Children’s Hospital (MCH) in Montreal, Canada. The authors approached each chapter with the practical reality in emerging and resource-poor countries in mind. We hope that this concept renders the manual use- ful and versatile in a variety of settings and diverse medical practices. To this end, we are proud of the manual’s endorsement by the International Society of Nephrology Global Outreach initiative and the support by the International Pediatric Nephrology Association. It is unavoidable in a practically oriented, abbreviated book like ours that topics are missing or only mentioned cursorily. The editors purposefully focused on rela- tively frequent and clinically important disorders and practical, mainly diagnostic and therapeutic, aspects. Detailed pathological and pathophysiological reviews were omitted to keep the text short and lean. The reader is strongly encouraged to seek in-depth information in more comprehensive textbooks. The editors appreciate speci fi c suggestions that help improve the utility and ame- liorate the shortcomings of this manual. Please, email the editors your comments. We hope that the global pediatric nephrology community will adopt the manual as a dynamic, interactive project with input from trainees and practitioners alike. The editors have an enduring commitment to research and education in pediatric renal diseases locally and internationally with the ultimate goal of improving chil- dren’s access to renal care – irrespective of monetary resources, societal status, or geography. They are connected through a long-standing collaboration within the ISN Sister Renal Center program. Kishore Phadke, Professor of Pediatrics and Nephrology, Director of the Children’s Kidney Care Center and former Chair of Pediatrics at St-John’s was the driving force behind this manual. He established a successful, internationally recognized Pediatric Nephrology Training Program, whose trainees now work across

  • Suprapubic Puncture in the Treatment of Neurogenic Bladder
    SUPRAPUBIC PUNCTURE IN THE TREATMENT OF NEUROGENIC BLADDER CHARLES C. HIGGINS, M.D. W. JAMES GARDNER, M.D. WM. A. NOSIK, M.D. The treatment of "cord bladder", a disturbance of bladder function from disease or trauma of the spinal cord, can be a difficult problem. Until the recent publications of Munro, there was little physiological basis for whatever treatment was instituted. With the advent of tidal drainage and recognition of the various types or stages of a given cord bladder, more satisfactory results have been obtained. In his excellent work on the cystometry of the bladder Munro1,2 classifies "cord bladders" into four groups: 1. Atonic — characterized by retention and extreme distention from lack of detrusor tone, lack of any activity of the external urethral sphincter, and complete lack of emptying contractions. 2. Autonomous — the detrusor and internal sphincter musculature show signs of reciprocal action of varying degree. There is an increase in detrusor muscle tone, and an inability to store an appreciable amount of urine without leakage. The condition of this bladder represents the end result in destructive lesions of the sacral segments or cauda equina. 3. Hypertonic — an expression of an uncontrolled spinal segmental reflex, characterized by a markedly increased detrusor muscle tone, almost constantly present emptying contractions, low residual urine, and impairment of control of the external sphincter. 4. Normal cord bladders — in transecting lesions above the sacral segments, consisting of two types which differ largely only in their cystometric findings: (a) Uninhibited cord bladder — an apparently normal bladder which empties itself quite regularly. The detrusor tone is still somewhat increased, emptying contractions are rhythmical, the residual is low, and the capacity is rather low.

  • Recommendations for the Management of Bladder Bowel
    & The ics ra tr pe a u i t i d c e s P Santos et al., Pediat Therapeut 2014, 4:1 Pediatrics & Therapeutics DOI: 10.4172/2161-0665.1000191 ISSN: 2161-0665 Review Article Open Access Recommendations for the Management of Bladder Bowel Dysfunction in Children Joana dos Santos1*, Abby Varghese2, Katharine Williams2 and Martin A Koyle2 1Division of Pediatric Nephrology and Medical Urology, The Hospital for Sick Children, Toronto, Canada 2Division of Pediatric Urology, The Hospital for Sick Children. Toronto, Canada Abstract Bladder Bowel dysfunction (BBD) represents a broad term used to describe a multitude of conditions associated with incontinence or Urinary Tract Infections (UTI) that commonly is seen in primary Family and/or Pediatrics care. The BBD spectrum includes lower urinary tract conditions such as overactive bladder and urge incontinence, voiding postponement, underactive bladder, and voiding dysfunction, and, importantly, also includes bowel issues, as constipation and encopresis. BBD is often not recognised by family or child or even the referring professional, but it is the secondary symptoms of wetting or UTI, that prompts the child to be evaluated by a consultant. The goal of this review is to provide a practical guideline for diagnosis and management of BBD in children, common problem in daily pediatric practice. Most importantly, considering that most of these issues are functional, is that the majority of these children are best evaluated and treatment instituted by the primary provider, with referral to a specialist, only in exceptional cases. Keywords: Bladder bowel dysfunction; Lower urinary tract importantly, most of these children likely can be evaluated and treatment symptoms; Dysfunctional elimination syndrome; Urinary tract instituted without early referral to a specialist.

  • Lower Urinary Tract Symptoms (LUTS) in Middle-Aged and Elderly Men
    Ⅵ Prostatic Diseases Lower Urinary Tract Symptoms (LUTS) in Middle-Aged and Elderly Men JMAJ 47(12): 543–548, 2004 Tomonori YAMANISHI Associate Professor, Department of Urology, Dokkyo University School of Medicine Abstract: Lower urinary tract symptoms (LUTS) include storage symptoms (previously termed as irritative symptoms), voiding symptoms (previously termed as obstructive symptoms) and post-micturition symptoms. The International Continence Society (ICS) published a new standardization of terminology of lower urinary tract function in 2002. Storage symptoms include increased daytime frequency, nocturia, urgency and incontinence. Of incontinence, stress, urge and mixed incontinence are the major symptoms, and ICS has also defined enuresis, continuous incontinence and giggle incontinence as other types of incontinence. Urgency, with or without urge incontinence, usually with frequency and nocturia, can be described as overactive bladder (OAB) syndrome, urge syndrome, or urgency/frequency syndrome. These syndromes suggest urodynamically demon- strable detrusor overactivity, but may be due to other forms of urethro-vesical dysfunction. Overactive bladder is an empirical diagnosis used as the basis for initial management after assessing lower urinary tract symptoms, physical findings urinalysis, and other indicated evaluation. Voiding symptoms include slow stream, splitting or spraying, intermittency, hesitancy, straining and terminal dribble. Post micturition symptoms include a feeling of incomplete emptying and post micturition dribble. The “feeling of incomplete emptying” symptom was formerly categorized as either a storage symptom or a voiding symptom, but has been categorized among the post micturition symptoms in the new ICS terminology. “Post micturition dribble” is the term used when an individual describes the involuntary loss of urine immediately after he/she has finished passing urine, usually in men after leaving the toilet.

Key words: Chyluria; Lymphatic; Pyelocaliceal system. INTRODUCTION Chyluria is the passage of chyle in the urine. The cause seems to be the rupture of retroperitoneal lymphatics into the pyelocaliceal system, giving urine a milky ap- pearance1-5. This communication is caused by the obstruction of lymphatic drainage proximal to intestinal lacteals, resulting in dilatation of distal lymphatics and the eventual rupture of lymphatic vessels into the urinary collecting system5-7. This con- dition if left untreated it leads to significant morbidity because of hematochyluria, recurrent renal colic, nutritional problems due to protein losses and immuno suppres- sion resulting from lymphocyturia. Various conservative measures like bed rest, high fluid intake, low-fat diet, fat-containing medium-chain triglycerides have been de- scribed. Chyluria may be classified as mild, moderate, or severe. Many sclerosing agents have been tried as silver nitrate, povidone iodine diluted in distillated water or pure. Povidone iodine with or without dextrose solution as a sclerosing agent was used successfully in a few studies.

Numerically, the public health problem of lymphatic filariasis is greatest in India, China and Indone- sia [1]. Lymphatic filariasis is caused by Wuchereria bancrofti, Brugia malayi, or Brugia timori. The clinical manifestations are directly related to the occlusion of the lymphatic channels, thereby causing lymphangiectasia [2]. The most common pre- sentations of lymphatic filariasis are subclinical microfilaremia, acute adenolymphangitis, hydrocele ,and chronic lymphatic disease[3].

The objective of the study was to investigate the diagnostic accuracy of single channel cystometry (SCC) for confirmation of neurogenic bladder following spinal cord injury. MATERIALS AND METHODS: The study was conducted in both out-patient and in-patient services of Department of Rehabilitation Medicine, Hospital Sungai Buloh, Malaysia. Subjects in the study include sixteen patients with a clinical diagnosis of neurogenic bladder following spinal cord injury aged between 15 and 62 years. Patients with a clinical diagnosis of neurogenic bladder were subjected to cystometric evaluation using SCC in our hospital. Confirmation of the diagnosis was made by urodynamic study (UDS) in another hospital. SCC procedure involved manual intra-vesical pressure assessment using a 12F Nelaton catheter. Cystometric parameter measurement taken in this study was detrusor pressure (cm H2O) done at regular intervals from baseline, throughout bladder filling phase and voiding/leaking phase. The relationship between detrusor pressure to bladder volume from initial bladder filling until voiding or leaking phase was recorded, analyzed and graph plotted. Maximum detrusor pressure (cm H2O) during bladder filling, voiding or leaking and the maximum cystometric capacity (mls) was recorded.
