Optimal clamping time in meatotomy procedure for children with meatal stenosis: Experience with 120 cases

OBJECTIVE

During meatotomy procedure for children with meatal stenosis (MS), a straight clamp used as a hemostat on the ventrum of the meatus before incised with scissors for clamping and holding bleeding from the site of operation. The aim of this study was to evaluate the optimum clamping time for meatotomy in children with MS.

MATERIALS AND METHODS

All the patients with MS between 2014 to 2019 were enrolled in this retrospective study. Patients with uncircumcised penis, traumatic catheterization, any kind of penile abnormality such as hypospadias or penile curvature, and active urinary tract infection (UTI) were excluded. The indication of meatotomy was a pinpoint meatus that develops with dorsal or lateral deflection of the urinary stream and high-velocity urine flow. During meatotomy procedure, clamping time was examined in different groups such as 2, 3, and 4 minutes. The main symptoms of presentation and ultrasonography (US) findings were recorded and compared between groups. To assess the optimum time clamping, postoperative bleeding was noted carefully in all groups. The success rate was recorded at onemonth postoperative follow-up in the clinic.

RESULTS

Of the 120 patients with MS who underwent a meatotomy procedure, there were 40 (33.3%) participants in each group. The main symptoms were painful urination and urine stream deviation that represented in 54 (46%) patients. Bladder wall thickness was the main pre-operation finding in the US which was observed in 67 (55.8%) patients. In comparison between the groups related to clamping time, bleeding was observed and required suturing when clamping was applied for 2 minutes in 4 (3.3%) patients (p = 0.016). With a minimum follow-up of 12 months, no recurrent meatal stenosis was reported.

CONCLUSIONS

Clamping time for more than 2 minutes may prevent bleeding during and after meatotomy.

Minor procedure, major impact: Patient-reported outcomes following urethral meatotomy

INTRODUCTION

Urethral meatotomy as treatment for meatal stenosis is a common pediatric urology procedure; however, little is known about the patient experience following this procedure.

OBJECTIVE

We aim to evaluate clinical factors associated with patient-reported symptom improvement after urethral meatotomy.

STUDY DESIGN

The families of boys undergoing urethral meatotomy between 2/2013 and 8/2016 received a survey by mail 6 weeks after surgery. Families were queried on changes in symptoms using a Likert-type scale (5 = much improved, 4 = somewhat improved, 3 = no change, 2 = somewhat worse, and 1 = much worse). Patient and procedure characteristics of the respondents were obtained via chart review. These included surgical indication(s) (abnormal stream, dysuria, or storage symptoms), postoperative complications, reoperation, and unplanned postoperative communications. Patients who had procedures other than simple urethral meatotomy were excluded. Descriptive statistics were compiled, and generalized estimating equations used to determine the associations of patient and procedure characteristics with symptom improvement.

RESULTS

We sent 629 surveys and received 194 responses (30.4%). Twelve respondents were excluded for complex procedures or miscoding. The majority of respondents were privately insured (74%) and were between 5 and 12 years old (45%) or 1 and 4 years old (42%). The most frequent surgical indication was abnormal stream (72%) followed by pain (21%) and storage symptoms (15.5%). Nine respondents had minor complications (4.9%). Four patients had restenosis requiring repeat urethral meatotomy. After surgery, a majority (79%) were "much improved," 16% were "somewhat improved," 3% had "no change," and 1% were "somewhat worse." No family reported "much worse." Those patients who had "abnormal stream" as a surgical indication were significantly more likely to report "much improved" (OR 1.83, p = 0.014) than those without. Patient-reported improvement was not associated with suture use, patient age, insurance, surgeon, or location of the procedure (Table).

DISCUSSION

Little has been written about patient-reported outcomes following urethral meatotomy. Our study affirms that the majority of boys improve following this procedure. However, improvement is significantly more likely if the child has a preoperative indication of an abnormal stream, such as deflection or spraying. Boys with symptoms of dysuria, frequency, or incontinence may be experiencing sequelae of meatal stenosis that simply take longer to improve. Alternatively, the meatal stenosis may be incidental to the primary symptoms.

CONCLUSIONS

A majority of families report substantial symptomatic improvement after urethral meatotomy. However, boys undergoing urethral meatotomy for reasons other than a urinary stream abnormality are less likely to experience improvement.
