Modern technique for penile torsion repair

Penile Degloving and Dorsal Dartos Flap Rotation Surgery in the Management of Severe Isolated Penile Torsion in a 6-Year-Old Boy

Penile torsion is a rare congenital anomaly that is usually characterized by a counterclockwise rotation of the penile shaft or glans. Although several surgical techniques for its correction have been proposed, the consensus of choosing the most efficient technique remains controversial. Herein, we report our operational approach that successfully corrected a severe (>90 degrees) isolated penile torsion in the form of penile degloving and dorsal dartos flap rotation surgery.

Procedures used for correction of isolated penile torsion: are they competitive or complementary?

OBJECTIVES

To report our experience in starting the correction of penile torsion, whatever its degree (moderate or severe) with one or more simple procedures either separately or complementary in the same session.

PATIENTS AND METHODS

Between 2013 and 2018, 62 patients who have significant isolated penile torsion (> 45°) were involved in this study. Those patients were subjected to either simple degloving with skin reposition, degloving with skin overcorrection and/or dartos flap procedures. Those procedures were performed either separately or complementarily. All patients were examined postoperatively after 7 days and followed up at 3, 6, and 9 months postoperatively.

RESULTS

37 out of 62 patients had a moderate degree (45-90) of penile torsion; 21 of them were corrected using skin degloving-reattachment technique, 11 patients were corrected by degloving with skin overcorrection, and in the remaining 4 patients dartos flap technique was used for correction. In 25/62 patients who had severe degree (> 90°) of torsion; 9 patients were managed by degloving with skin overcorrection, while in 13 patients the procedure was shifted to dartos flap technique, and the remaining 3 patients, 2 of whom had 180° torsion, were managed by dartos flap with added skin overcorrection.

CONCLUSION

Performing degloving and skin reattachment with or without skin overcorrection procedure and dartos flap procedure either separately or complementarily in the same patient whatever the degree of torsion (moderate or severe) is associated with good results and can protect some patients from exposure to more difficult and extensive procedures as corporopexy and corporeal plication.

The Fisher Technique for Correction of Penile Torsion in Children: Who Are the Candidates?

OBJECTIVE

To report our experience in the treatment of penile torsion with a special reference to the Fisher technique.

PATIENTS AND METHODS

We reviewed 30 cases of congenital penile torsion treated from 2009 to 2015 in a single center. Sixteen patients presented a moderate rotation of 45°-90° and 14 had a severe rotation with an angle greater than 90°. Chordee was present in 17 cases and distal glanular hypospadias in 15 cases. Median age at surgery was 10 months. In 14 cases, degloving along with skin realignment, alone, allowed correction of the torsion. In 16 cases, the Dartos flap (Fisher technique) was used.

RESULTS

Out of the 30 patients, 29 had a good result, with a complete correction of the torsion. Only 1 patient had a residual torsion of 30°. Complications were minor and consisted of skin excess in 11 patients; 1 single case needed to be reoperated for that skin complication. The need for the Dartos flap procedure was significantly correlated to the degree of torsion (P = .001): it was used in 4 out of 16 patients (25%) with a torsion of less than 90°, and in 12 out of 14 patients (86%) with a torsion of 90° or more.

CONCLUSION

Most of penile rotations less than 90° can be corrected by skin degloving and realignment. The Fisher technique is a simple and safe procedure for correction of persistent rotation after skin degloving; such cases have usually a penile rotation greater than 90°.

Penile degloving and dorsal dartos flap rotation approach for the management of isolated penile torsion

OBJECTIVE

Penile torsion is a counterclockwise rotational anomaly of the penile shaft or glans. We aimed to evaluate the outcomes of penile degloving and dorsal dartos flap rotation used for the repair of isolated penil torsion.

MATERIAL AND METHODS

During evaluation of the patients admitted to our polyclinic for circumcision between January 2013-December 2014, 5 cases of isolated penile torsion were determined. Following the circumcision procedure performed with bipolar cautery, patients undergoing penile degloving were checked whether penile torsion was relieved or not. In case of insufficient improvement, torsion was corrected with application of dorsal dartos flap. Penile torsion was corrected with dartos flap in 2, and penile degloving in 3 cases.

RESULTS

The mean age of the patients was 5.6 years (4-7), and the mean operative time 12 minutes (7-20), respectively. The mean operation time was 17.5 (15-20) minutes and 8.3 (7-10) minutes in the dorsal dartos flap and penile degloving groups, respectively. The preoperative mean degree of penile torsion was 50° (30°-70°). The mean degree of torsion was 65° and 40° in the dorsal dartos and penile degloving groups, respectively. During the postoperative follow up, 1 case of residual torsion (<10°) was observed in the dorsal dartos flap group. Residual torsion was not observed in other patients.

CONCLUSION

Exploration for isolated cases of penile torsion during the circumcision procedure should not be overlooked. Successful results can be obtained with penile degloving and dartos flap rotation in cases with low and moderate torsion.

Benign penile skin anomalies in children: a primer for pediatricians

BACKGROUND

Abnormalities involving the skin coverage of the penis are difficult to define, but they can significantly alter penile appearance, and be a cause of parental concern.

DATA SOURCES

The present review was based on a nonsystematic search of the English language medical literature using a combination of key words including "penile skin anomalies" and the specific names of the different conditions.

RESULTS

Conditions were addressed in the following order, those mainly affecting the prepuce (phimosis, balanitis xerotica obliterans, balanitis, paraphimosis), those which alter penile configuration (inconspicuous penis and penile torsion), and lastly focal lesions (cysts, nevi and vascular lesions). Most of these anomalies are congenital, have no or minimal influence on urinary function, and can be detected on clinical examination. Spontaneous improvement is possible. In the majority of cases undergoing surgery, the potential psychological implications of genital malformation on patient development are the main reason for treatment, and the age generally recommended for surgery is after 12 months of age.

CONCLUSION

This review provides the pediatrician with a handy tool to identify the most common penile skin anomalies, counsel parents adequately, make sensible and evidence based choices for management, and recognize complications or untoward outcomes in patients undergoing surgery.

Penile torsion repair in children following a ladder step: simpler steps are usually sufficient

OBJECTIVE

To evaluate the correction of different degrees of penile torsion following a ladder step so that simpler steps are used whenever possible. This can avoid the morbidity and complications of complex procedures.

PATIENTS AND METHODS

Cases of congenital and acquired penile torsion were repaired on a ladder step basis irrespective of the degree of torsion, starting with degloving and skin realignment, then a dorsal dartos flap and finally corporopexy. The torsion is checked with artificial erection after each step, and if corrected completely then the next step(s) is omitted.

RESULTS

Twenty-five cases of penile torsion (30-180°) were repaired over a 4-year period. Three cases were corrected by degloving only, 12 by degloving and skin realignment, five by a dartos flap and four required a corporopexy. Postoperative complications included five cases of penile edema, one case of hematoma and one case of dorsal skin gangrene. Residual torsion of <15° occurred in three cases. No cases required redo surgery.

CONCLUSION

A ladder step approach is a good option for penile torsion repair, starting with simpler techniques until complete correction is achieved. There is no need to plan a complex procedure in advance.

Dorsal dartos flap rotation versus suturing tunica albuginea to the pubic periosteum for correction of penile torsion: a prospective randomized study

PURPOSE

To compare the results of dorsal dartos flap rotation versus suturing tunica albuginea to the pubic periosteum for correction of congenital penile torsion.

PATIENTS AND METHODS

Seventeen patients with congenital penile torsion were evaluated and managed from 2006 to 2010. On a random basis, 9 patients underwent surgical repair using a dorsal dartos flap rotation technique (group 1), and 8 patients by suturing tunica albuginea to the pubic periosteum (group 2). All were followed up every 6 months.

RESULTS

The mean age in group 1 was 52.3 ± 24.8 months, while in group 2 it was 53.4 ± 33.6 months. Mean follow up was 22.3 ± 10.2 and 21.5 ± 7.2 months in group 1 and group 2 respectively. Torsion was corrected in 6 (66.7%) patients of group 1; 3 (33.3%) had residual torsion < 10°. In group 2, correction was achieved in 6 (75.0%) patients and 2 (25.0%) had residual torsion < 10°. The mean operative time was significantly less for group 1 than for group 2: 45.3 ± 7.1 and 74.5 ± 5.3 min, respectively (P < 0.0001).

CONCLUSIONS

In short-term prepubertal follow up, both dorsal dartos flap rotation and suturing tunica albuginea to the pubic periosteum are effective for correction of congenital penile torsion. The former technique is easier to perform as it requires much less dissection.

Elements of morphology: standard terminology for the external genitalia

An international group of clinicians working in the field of dysmorphology has initiated the standardization of terms used to describe human morphology. The goals are to standardize these terms and reach consensus regarding their definitions. In this way, we will increase the utility of descriptions of the human phenotype and facilitate reliable comparisons of findings among patients. Discussions with other workers in dysmorphology and related fields, such as developmental biology and molecular genetics, will become more precise. Here we introduce the anatomy of the male and female genitalia, and define and illustrate the terms that describe the major characteristics of these body regions. Published 2013.

The management of moderate and severe congenital penile torsion associated with hypospadias: Urethral mobilisation is not a panacea against torsion

Objectives

To evaluate the effectiveness of urethral mobilisation for correcting moderate and severe penile torsion associated with distal hypospadias.

Patients and methods

Nineteen patients with distal hypospadias and congenital moderate and severe penile torsion were treated surgically. The hypospadias was at the distal shaft, coronal and glanular in seven, eight and four patients, respectively, and six had mild chordee. The mean (SD, range) angle of torsion was 94.7 (19.9, 75–160)°. The urethra was mobilised down to the perineum. If the urethral mobilisation was insufficient the right border of the tunica albuginea was anchored to the pubic periosteum. The hypospadias was repaired using the urethral mobilisation and advancement technique, with a triangular plate flap for meatoplasty. The patients were followed up for 12–18 months.

Results

All patients had a successful functional and cosmetic outcome, with no residual torsion. Two patients had a small subcutaneous haematoma that resolved after conservative treatment. Massive oedema occurred in three patients and was treated conservatively. Urethral mobilisation did not correct the penile torsion completely. Although the mean (SD, range) angle of torsion was reduced to 86.1 (14.3, 65–130)°, statistically significantly different (P = 0.001), it was not clinically important. The presence of chordee had no significant correlation with the reduction of penile torsion.

Conclusion

Urethral mobilisation cannot completely correct moderate and severe penile torsion but it might only partly decrease the angle of torsion. Periosteal anchoring of the tunica albuginea might be the most reliable manoeuvre for the complete correction of penile torsion.
