Common office problems in pediatric urology and gynecology

Wedge urethral meatotomy in meatal stenosis secondary to web formation

INTRODUCTION

Meatal stenosis is a common acquired urological problem facing pediatric surgeons and urologists. It can affect both the circumcised and non-circumcised boys with a higher incidence in the non-circumcised boys because of the increased risk of penile inflammatory conditions, most commonly lichen sclerosis and urinary tract infection, and in the most recent meta-analysis study, the incidence of meatal stenosis following circumcision is only 0.65%. Urethral meatal web is a common cause of meatal stenosis after circumcision (Fig. 1). Symptoms of meatal stenosis are not evident in non-toilet trained infants. However, in older boys, an abnormal upward direction of urine stream while urinating with a long narrow stream, dysuria, burning at the meatus, blood spot at the meatus, frequency, prolonged urination and recurrent urinary tract infection are the common presenting symptoms. Surgical correction of meatal stenosis is done by either meatotomy or meatoplasty.

OBJECTIVE

We describe a novel modification in the classical urethral meatotomy technique, which is wedge urethral meatotomy, and assess the outcome of this procedure in managing meatal stenosis secondary to a meatal web.

PATIENTS AND METHOD

A prospective study was conducted on 60 cases of symptomatic meatal stenosis due to a thin ventral web treated in the pediatric surgical centre in Mosul city from October 2018 until April 2021.

EXCLUSION CRITERIA

Patients with meatal stenosis not accompanied by web, patients with a thick ventral web (requiring suturing technique), and those with hypospadias or other associated urinary disorders (like VUR) were excluded from the study.

SURGICAL TECHNIQUE

In all cases, the procedure was performed under general anaesthesia and by a single surgeon (the author). A wedge (V-shaped) 2-3 mm long excision of the thin ventral meatal web made after applying a hemostat in three directions (ventral midline and two lateral crushes) (Figs. 2 and 3). The procedure did not require suturing or Foley catheterization. The operative time was ranged from 4 to 6 min (mean 5 min). Postoperatively, The parents were instructed to separate both edges of the meatus three times daily for ten days, together with applying Fucidin cream locally with oral cefixime and paracetamol.

RESULTS

The age of the 60 patients ranged between 6 months and 10 years old (median age 38 months) (Fig. 4). Two (3%) patients developed mild meatal stricture, which did not require further intervention as their urine stream remained straight with accepted calibre. The remaining 58 (97%) cases did well postoperatively apart from temporary dysuria in 23 (38%) patients, evident in the first 2-3 days postoperatively. They had a single straight urinary stream while urinating with a good calibre meatus (Figs. 2(D), 3(D) and 5), and during short term follow up, there is a substantial reduction in the frequency of urinary tract infections.

DISCUSSION

Although two (3%) cases developed mild postoperative meatal stricture, none of them required redo surgery compared with a study done by Godley SP in 2015, which showed a reoperation rate after formal meatotomy of 2%. Cartwright in 1996 had a 2% reoperation rate after office meatotomy. Another study in 2018 also reported a reoperation rate of 2.2%. The reason for restenosis that necessitates revision surgery in the above studies may be refusion of the cut edge of the web after meatotomy, which was not a concern in wedge urethral meatotomy in which the web excised and not incised. In 2017, Özen MA applied the same procedure on 13 boys complaining from meatal web after circumcision. The technique involved excision of the web, and two stitches were inserted at 5 and 7 o'clock using 7/0 Polydiaxonone suture with excellent final results. In our study, suturing was not applied, so spraying or divided urinary stream (although temporary) was not observed in the postoperative period as seen in meatoplasty or in cases of meatotomy that require suturing technique. This point was satisfactory for patients and parents.

CONCLUSION

Wedge urethral meatotomy represents a novel modification in the formal meatotomy technique, which can be applied in meatal stenosis secondary to a thin ventral web with satisfactory results, as reoperation after this procedure was not recorded.

Surgical management of meatal stenosis with meatoplasty

Meatal stenosis is a common urologic complication after circumcision. Children present to their primary care physicians with complaints of deviated urinary stream, difficult-to-aim, painful urination, and urinary frequency. Clinical exam reveals a pinpoint meatus and if the child is asked to urinate, he will usually have an upward, thin, occasionally forceful urinary stream with incomplete bladder emptying. The mainstay of management is meatoplasty (reconstruction of the distal urethra /meatus). This educational video will demonstrate how this is performed.

Vaginal microbiocoenosis and cytology of prepubertal and adolescent girls: their role in health and disease

BACKGROUND

Clinicians and investigators often do not appreciate the importance of vaginal microbiocoenosis and vaginal cytology in the health of prepubertal and adolescent girls.

DATA SOURCES

Based on recent publications in human medicine and our own experience with vaginal cytology and microbiology in children and adolescent girls, we review the principles of vaginal microbiocoenosis and cytology and their roles in disease prevention in prepubertal and adolescent girls.

RESULTS

The main role of vaginal microbiocoenosis and cytology in diagnosing as well as developing vulvovaginitis is demonstrated. Clinicians can identify states of vaginal health and disease by important well-known diagnostic tools, including vaginal cytology. Lactobacilli are infrequently observed in the prepubertal girls, but become more abundant in adolescent girls. Three basic types of vaginal smears are presented in addition to a classification of inflammatory urogenital diseases. Management of common types of vulvovaginitis is also considered.

CONCLUSIONS

This essential shift in vaginal biocoenosis is important to prevent the growth of potentially pathogenic flora in the vagina. The detection of vaginal microbiocoenosis problems and recognition of changing cytology in vaginal development can provide helpful clues to identifying and preventing vaginal diseases in this pediatric population.

THE EFFICACY OF LMX VERSUS EMLA FOR PAIN RELIEF IN BOYS UNDERGOING OFFICE MEATOTOMY

PURPOSE

We determined if a difference in pain management occurred when topical anesthetics LMX (formerly ELA-Max, lidocaine 4%) and EMLA (lidocaine 2.5% and prilocaine 2.5%) were compared in boys undergoing office meatotomy for symptomatic meatal stenosis.

MATERIALS AND METHODS

A prospective randomized study was performed on 52 boys who underwent office meatotomy by a single pediatric urologist. Of the boys 26, 2 to 9 years old (mean age 4.4) underwent meatotomy 45 minutes after topical anesthetic application (LMX 13, EMLA 13) between February and December 2001, 26, ages 1 to 10 years old (4.6) underwent meatotomy 30 minutes after topical anesthetic application (LMX 13, EMLA 13) between April 2002 and January 2003. A single pediatric urological nurse performed pain assessment using the Wong-Baker Faces scale before applying the anesthetic ointment and immediately following the procedure. Each child had either LMX or EMLA applied and covered with an occlusive dressing for either 45 or 30 minutes before the procedure. Oral acetaminophen (10 mg/kg) was given at the time of anesthetic application. A meatotomy was then performed using a straight crushing hemostat for 1 to 2 minutes followed by incision. Mann-Whitney rank sum test was implemented to determine statistical significance.

RESULTS

Excellent procedure outcomes were experienced by all patients without recurrent meatal stenosis.

CONCLUSIONS

There was no significant difference between LMX and EMLA when applied 45 minutes before meatotomy. When applied 30 minutes before meatotomy LMX provided significantly superior pain management than EMLA.

Urologic emergencies

Genitourinary emergencies are commonly seen in the emergency room, and the primary care physician plays a vital role in the initial evaluation and treatment of each. Although genitourinary trauma is rarely life threatening, it may be the cause of significant long-term morbidity. Key clinical indicators outlined in this article (eg, inability to urinate, gross hematuria) combined with judicious use of imaging help stage the injury and allow a safe and rational approach to treatment. The acute scrotum frequently presents a challenging problem to both the emergentologist and urologist. Although epididymitis may be managed nonoperatively, there should be no delay in exploring suspected testis torsion. The conditions of the penis outlined require urgent treatment to preserve potency (priapism) and restore normal function (eg, penile amputation). Acute urinary retention has a myriad of underlying etiologies, and treatment must be individualized. Urgent bladder decompression by urethral or suprapubic catheterization provides initial relief until urologic consultation is available.

Diseases of the foreskin, penis, and urethra

Diseases of the foreskin, penis, and urethra are uncommon conditions that constitute a small percentage of emergency department visits. However, it is important that the emergency physician recognize and treat these conditions and understand which conditions require urologic consultation. Rapid and proper treatment in the emergency department can alleviate patient discomfort, increase patient satisfaction, and prevent future morbidity.

Cost-effectiveness analysis of treatments for phimosis: a comparison of surgical and medicinal approaches and their economic effect

OBJECTIVE

To compare the cost-effectiveness of surgery and topical steroids as treatments for phimosis (defined as a clinically verifiable, pathological, cicatricial stenosis of the prepuce) and to evaluate the financial basis of these treatments.

METHODS

Data on treatment using topical steroids was obtained from published reports and those for circumcision from claims by private hospitals for children < 13 years old registered at the health insurance department of our facility. The estimate of the French national financial cost of the treatments for 1998 was calculated from public and private institutional information.

RESULTS

Treatment with topical steroids for 4-8 weeks was successful in approximately 85% of patients (mean age 5 years) and had no side-effects; the remaining 15% were treated by circumcision. Topical steroid therapy costs (in French francs) F 360 per patient. For those primarily treated by circumcision (81 boys, mean age 4.3 years) and diagnosed as having phimosis, the cost was F 3330 per patient in the private sector. The total number of circumcisions performed in France, regardless of sector (public or private) for 1998 was estimated to be 51 080, which represents an annual cost of F 195.7 million.

CONCLUSION

As topical pharmacological treatment avoids the disadvantages, trauma and potential complications of penile surgery, including anaesthesia-related risks, the use of topical steroids as a primary treatment appears to be justified in boys with clinically verifiable phimosis. This treatment could reduce costs by 75%, which represents a potential annual saving of approximately F 150 million.

Office pediatric urologic procedures from a parental perspective

OBJECTIVES

To determine the parent perception of discomfort (PPD) in children receiving local anesthesia for the lysis of labial adhesions, meatotomy, and newborn circumcision; the parents' perceived outcome of these procedures; and the overall satisfaction of parents when these procedures are performed in the office.

METHODS

A confidential phone survey was given to 99 parent participants whose children had received local anesthesia for the lysis of labial adhesions (n = 14), meatotomy (n = 28), or newborn circumcision (n = 57). Parents in the labial adhesion and meatal stenosis groups were asked to rate their child's level of discomfort (PPD) during the procedure as mild (1), moderate (2), or severe (3), and those in the circumcision group were asked to use the same scale to rate their child's discomfort after the procedure. Parents were also asked whether they thought the procedure was successful and whether they were satisfied with their decision to have it done in the office using local anesthesia.

RESULTS

Among the labial adhesion, meatotomy, and circumcision groups, the mean PPD +/- SD was 1.64 +/- 0.75, 1.54 +/- 0.69, and 1.21 +/- 0.53, respectively. The observed procedures, lysis of labial adhesions and meatotomy, had a significantly higher PPD score (P = 0.005) than the unobserved procedure (circumcision). Parents reported good outcomes in 94 (94.9%) of 99 children, with 4 girls experiencing recurrent labial adhesions and 1 boy experiencing recurrent meatal stenosis. Overall, 95 (96.0%) of 99 parents stated that they were satisfied with their decision to have the procedure done in the office with local anesthesia. Of the remaining 4 parents, 3 parents in the circumcision group stated they would have preferred general anesthesia, and 1 parent in the labial adhesion group was undecided.

CONCLUSIONS

The PPD is greater if the parent observes their child's procedure. However, office procedures using local anesthesia for the lysis of labial adhesions, meatotomy, and newborn circumcision are well accepted among the parent population.
