Kidney Blow Out Due to Inguinal Herniation of the Ureter in an Infant.

Ureteroinguinal herniation is a rare event, usually diagnosed during the surgical repair of inguinal hernias. Here, we describe the first case of a kidney blow out due to this condition in a male infant.

Hypospadias, all there is to know.

Hypospadias is one of the most common congenital anomalies in men. The condition is typically characterized by proximal displacement of the urethral opening, penile curvature, and a ventrally deficient hooded foreskin. In about 70%, the urethral meatus is located distally on the penile shaft; this is considered a mild form that is not associated with other urogenital deformities. The remaining 30% are proximal and often more complex. In these cases, endocrinological evaluation is advised to exclude disorders of sexual differentiation, especially in case of concomitant unilateral or bilateral undescended testis. Although the etiology of hypospadias is largely unknown, many hypotheses exist about genetic predisposition and hormonal influences. The goal of hypospadias repair is to achieve cosmetic and functional normality, and currently, surgery is recommended between 6 and 18 months of age. Hypospadias can be corrected at any age with comparable complication risk, functional, and cosmetic outcome; however, the optimal age of repair remains conclusive. Although long-term overall outcome concerning cosmetic appearance and sexual function is fairly good, after correction, men may more often be inhibited in seeking sexual contact. Moreover, lower urinary tract symptoms occur twice as often in patients undergoing hypospadias repair and can still occur many years after the initial repair. CONCLUSION: This study explores the most recent insights into the management of hypospadias. What is Known: • Guidelines advise referral for treatment between 6 and 18 months of age. • Cosmetic outcome is considered satisfactory in over 70% of all patients. What is New: • Long-term complications include urinary tract symptoms and sexual and cosmetic issues. • New developments allow a more individualized approach, hopefully leading to less complications and more patient satisfaction.

[A boy with a painful lump in the right inguinal region]. / Een jongen met pijnlijke zwelling in lies.

A 6-year-old male, with no history of importance, was seen in the Emergency Department, presenting with a painful lump in the right inguinal region since four days. An ultrasound revealed a torsion of an ectopical testis. Surgery showed a necrotic right testicle and a right orchiectomy was performed.

[A boy with cyclic vomiting and an alleged furosemide allergy on the basis of a subpelvic stenosis]. / Een jongen met cyclisch braken en een vermeende furosemideallergie op basis van een subpelviene stenose.

An 8-year-old boy, known with a Diamond-Blackfan anaemia, was admitted to the hospital because of frequent vomiting since 3 days and loin pain. In previous years, he had been admitted several times for the same complaints but no cause had been identified. Ultrasound examination of the abdomen performed at admittance showed dilatation of the left renal pelvis. A renal scintigraphy was discussed with the mother, and she refused the injection of furosemide, because her son was allegedly allergic to furosemide: previous furosemide treatments during blood transfusions for his anaemia had always resulted in stomach-ache and vomiting, which may be attributed, however, to an acute dilatation of the renal pelvis due to the diuretic effect of furosemide. Scintigraphy without furosemide showed a significant obstruction and asymmetric renal function, so a pyeloplasty was performed after which he has been symptom-free. In patients with cyclic vomiting, an intermittent uretero-pelvic junction obstruction should be considered and can only be ruled out when ultrasound during the complaints and renal scintigraphy under adequate hydration and after furosemide are normal.

[The undescended testis: arguments in favour of early treatment, provided retractile testis and acquired non-scrotal testis have been excluded]. / De niet-scrotale testis: argumenten vóór vroeg behandelen, mits retractiele testis en verworven niet-scrotale testis zijn uitgesloten.

--Guidelines for the treatment ofundescended testis (UDT) are sparse. Often an operation in the second year of life is advised. --Recent data indicate that the normal maturation process, which will ultimately lead to a normal quantity and quality of germ cells, is impaired as early as in the first half year of a newborn's life. None of the guidelines take this into account. Spontaneous descent after the fourth month following birth, of testes that have previously not descended, hardly ever occurs. --No differences have been shown in complication numbers between surgery before and after the first birthday. Orchidopexy prior to the 13th birthday reduces the risk of testicular cancer. --Therefore, based on these data, it is advised to perform orchidopexy in the second half of the first year of a newborn's life. In older boys a UDT must be treated before the 13th birthday. --In the Netherlands a lot more orchidopexies are done despite what may be expected based on prevalence numbers of UDT: testes retaining a normal volume that would most probably have descended spontaneously come puberty. --It remains important to carry out a careful physical examination and document the position of the testes soon after birth, and later on if UDT is suspected, to avoid unnecessary operations on retractile testes and acquired UDT.

High level of patient satisfaction and comfort during diagnostic urological procedures performed by urologists and residents.

OBJECTIVE: The aim of this study was to investigate how patients experience diagnostic urological procedures performed by urologists, junior residents and senior residents, and to assess the influence of procedure-related factors on patient experiences. METHODS: Data were collected during 222 procedures: 84 transrectal ultrasound-guided prostate biopsies (TRUSP; urologists n = 39, residents n = 45) and 138 urethrocystoscopies (UCS; urologists n = 44, residents n = 94) in six hospitals. Patient experiences were assessed using a questionnaire focusing on pain, comfort and satisfaction (visual analogue scale, 0-10) and communication aspects on a four-point Likert scale. Clinical observations were made to identify influencing factors. RESULTS: Median values for patient experiences across procedures were 10 (range 5-10) for patient satisfaction, 2 (0-9) for pain and 8 (0-10) for comfort. Generalized estimating equations revealed no significant differences between urologists, senior residents and junior residents in terms of experienced patient comfort, satisfaction or pain. Procedural time was longer for residents, but this did not correlate significantly with patient-experienced comfort (p = 0.3). In UCS, patient comfort and satisfaction were higher in the supine position for male and female patients, respectively (p < 0.01). In TRUSP, local anaesthesia resulted in a significant decrease in pain (p = 0.002) and an increase in comfort (p = 0.03). Finally, older patients experienced less pain and gave higher comfort and satisfaction responses than younger patients. CONCLUSIONS: Patients expressed high levels of satisfaction and comfort during diagnostic urological procedures. Experiences were not affected by the level of training, suggesting highly developed interpersonal and communication skills for residents in an early stage of residency training. Patients demonstrated significant preferences for local anaesthesia in TRUSP and performance of UCS in the supine position over the lithotomy position.

[Urethral meatal stenosis in boys easily overlooked]. / Urethrale-meatusstenose bij jongens gemakkelijk gemist.

Three boys aged 8, 5, 3 and 9 years, respectively, appeared to have urethral meatal stenosis. In the first patient this appeared during a check-up following treatment for balanitis. Patient history revealed that his micturition duration was longer than before. In the second patient, who underwent surgical correction for hypospadia, it was discovered because he took longer to urinate than his brother. In the third patient stenosis was observed during an appointment for a retracted testicle; he had been circumcised earlier for cultural reasons. Meatomy was performed under anaesthesia in all 3 patients, after which the micturition duration and stream velocity were normal. The third patient continued to have an extremely large bladder capacity and residual volume. Meatal stenosis may lead to obstructive uropathy, urinary tract infection and eventually damage to renal parenchyma. Symptomatic presentation can be late. Diagnostic tests include urine analysis and culture, and uroflowmetry. Visual inspection by spreading the meatal dimple to visualise a pinhole urethra cannot be overemphasised.

Therapeutic approach to Candida bezoar in children.

INTRODUCTION: Candida bezoar (CB) is a rare finding in neonates and infants with candiduria, presenting as necrotic debris with proliferating mycelia in the collecting system of the kidney. If initial antifungal medical treatment does not result in clearance of candiduria and disappearance of CB on ultrasound in dilated kidneys, invasive interventions like insertion of nephrostomy tubes (NT) or surgical interventions to drain the kidney are sometimes advocated(.). However, NT placement can be a technical challenge, especially in pre- and dysmature neonates, and NT displacement or obstruction by the CB can lead to suboptimal treatment. Identification of those children who will benefit from invasive renal drainage is important. OBJECTIVE: This study evaluates the management of patients with CB in three tertiary referral hospitals to determine criteria for intervention. MATERIALS AND METHODS: A retrospective multicenter chart analysis was conducted of children with candiduria and ultrasonographic demonstration of CB (diagnosed between March 1995 and August 2012). The indication for invasive renal drainage (if performed) and subsequent clinical outcome, serum creatinine levels and ultrasound findings were assessed. RESULTS: A total of 12 children were included, two of which were premature neonates. Eight children had congenital urogenital anomalies. One older child with acute myeloid leukemia had CB during chemotherapy and one ex-premature developed CB following cerebral candidiasis. All children received systemic antifungal medication; in seven children invasive treatment was added. Indications for invasive treatment were clinical deterioration, progressive renal dilation, pyonephrosis, rising creatinine levels and persistence of CB. Two underwent a Y-cutaneous ureterostomy and nephrostomy tubes were inserted in five children. Percutaneous renal drainage by nephrostomy led to complications in 3 of 6 procedures. In all patients, irrespective of therapeutic modality, follow-up ultrasound demonstrated no de novo changes. No additional parenchymal defects or deterioration of split renal function were seen on DMSA or MAG-3 scan. DISCUSSION: In the literature renal drainage is suggested in case of complete obstruction. However dilatation is a frequent finding in children as part of the congenital renal anomaly and does not necessarily mean that there is obstruction of the urinary tract. Even in children without candida infections the diagnosis of obstruction is not straightforward, while the results of a MAG 3 scan can be obscured by compromised kidney function, parenchymal bacterial infiltration and neonatal immaturity of the kidney. If candiduria and CB persist despite intensive medical treatment, intensive consultation is required before renal drainage, because NT insertion might be a surgical challenge. Complications such as displacement of the NT, urinoma development, or NT obstruction can occur and was seen in three of six procedures. Premature neonates seem to be more prone to complications due to their small anatomical proportions, requiring medical equipment with small diameters prone to displacement and obstruction. Some studies describe successful pharmaceutical management in the majority of patients with CB. Other studies describe unilateral surgical intervention in children with bilateral CB where unilateral drainage did not influence overall renal outcome. This is in line with our results. A limitation of the present study is its retrospective design. In this population, the motivation for invasive renal drainage or conservative management was not well documented in all cases, and was mainly based on clinical and diagnostic parameters like creatinine levels and radiographic findings. CONCLUSION: Renal drainage should be considered in selected cases after failure of systemic antifungal treatment. Inserting and maintaining a nephrostomy tube in young children is associated with a high rate of complications; conservative treatment is likely to be sufficient in the majority of patients with candiduria and CB.

[The wet umbilicus: maybe not an umbilical granuloma?]. / De nattende navel: misschien geen navelgranuloom?

Three infants, 1 girl aged 10 months and 2 boys aged 2 and 4 months, presented with a discharging umbilicus directly or shortly after birth. Echography and cystography showed three different causes: a cystic remnant of the omphalomesenteric duct, a persistent urachus and a persistent omphalomesenteric duct. All were successfully managed surgically. The most common cause of a discharging umbilicus is an umbilical granuloma. This is usually treated by application of silver nitrate. In some patients, however, the discharge may not disappear or may contain urine or faecal material. These cases should be referred and echography performed. In case of an anomaly of the urachus or the omphalomesenteric duct, surgical exploration is mandatory. The lesion should be excised en bloc, together with a part of the bladder or the bowel.
