prepubertal phimosis, congenital or physiologic
reassurance and hygiene
In patients with congenital or physiologic phimosis, the best treatment is simply observation over time.
Expectant management for congenital (physiologic) phimosis is preferred up to the time of puberty (typically around 12 years of age).[11]European Association of Urology; European Society for Paediatric Urology. EAU guidelines on paediatric urology. Apr 2024 [internet publication]. https://uroweb.org/guidelines/paediatric-urology [46]The Royal Children's Hospital Melbourne. Clinical practice guidelines: the penis and foreskin. Jul 2018 [internet publication]. https://www.rch.org.au/clinicalguide/guideline_index/The_penis_and_foreskin
Reassurance to parents and child about normal penile anatomy and proper hygiene (without the need to forcibly retract the foreskin) will generally suffice. Routine cleaning of the external skin is desirable, but it is not necessary to retract the phimotic foreskin for cleaning until natural separation of the foreskin occurs.[42]Dave S, Afshar K, Braga LH, et al. Canadian Urological Association guideline on the care of the normal foreskin and neonatal circumcision in Canadian infants (full version). Can Urol Assoc J. 2018 Feb; 12(2):E76-99. https://www.cua.org/guidelines http://www.ncbi.nlm.nih.gov/pubmed/29381458?tool=bestpractice.com
topical corticosteroids
Treatment recommended for SOME patients in selected patient group
Presence of cicatrix or BXO/lichen sclerosis requires treatment regardless of age.
Success rates of 83% have been reported at a median follow-up of 22 months among prepubertal boys (n=462; mean age 4.7 years), including 67% of patients with BXO.[49]Ghysel C, Vander Eeckt K, Bogaert GA. Long-term efficiency of skin stretching and a topical corticoid cream application for unretractable foreskin and phimosis in prepubertal boys. Urol Int. 2009;82(1):81-8. http://www.ncbi.nlm.nih.gov/pubmed/19172103?tool=bestpractice.com
Treatment course: 4 to 6 weeks. Course may be repeated once. Care should be taken to educate the patient and family on proper application techniques of topical corticosteroids.
Primary options
betamethasone dipropionate topical: (0.05%) apply sparingly to the preputial outlet twice daily
OR
triamcinolone topical: (0.1%) apply sparingly to the preputial outlet twice daily
preputial surgery
Treatment recommended for SOME patients in selected patient group
Patients with phimosis who do not respond to or cannot tolerate a course of properly applied topical corticosteroid are managed with circumcision.[11]European Association of Urology; European Society for Paediatric Urology. EAU guidelines on paediatric urology. Apr 2024 [internet publication]. https://uroweb.org/guidelines/paediatric-urology [35]McGregor TB, Pike JG, Leonard MP.

A preputioplasty consists of limited dorsal slit(s) with transverse closure made along the constricting band of skin. Preputioplasty can be an effective alternative to full circumcision in most children; however, patients with BXO should undergo standard circumcision.[51]Cuckow PM, Rix G, Mouriquand PD.

Acquired or pathologic phimosis (e.g., cicatrix or balanitis xerotica obliterans [BXO]/lichen sclerosis) requires treatment regardless of age.
Treatment course: 4 to 6 weeks. Course may be repeated once. Care should be taken to educate the patient and family about the proper application of topical corticosteroids.

paraphimosis
manual reduction
Paraphimosis should be managed with immediate manual reduction. [Figure caption and citation for the preceding image starts]: ParaphimosisFrom the collection of Nicol Corbin Bush, MD [Citation ends].
The goal of treatment is prompt reduction of the foreskin to its normal anatomic position (distal to the glans penis).
To perform manual reduction, adequate anesthesia is administered in the form of dorsal penile nerve block or ring block with local anesthetic (lidocaine or bupivacaine, without epinephrine). Children may require conscious sedation and/or general anesthesia. Circumferential pressure around the edematous ring of foreskin for several minutes may help reduce the edema. Both thumbs are placed on the glans with the fingers wrapped around the shaft of the penis proximal to the foreskin. Gentle pressure is applied to pull the foreskin with the fingers and push the glans with the thumbs until the foreskin is reduced to its anatomic position.[53]Little B, White M. Treatment options for paraphimosis. Int J Clin Pract. 2005 May;59(5):591-3. http://www.ncbi.nlm.nih.gov/pubmed/15857356?tool=bestpractice.com Water-based lubrication may facilitate preputial reduction.[54]American Urological Association. Urologic emergencies. Nov 2022 [internet publication]. https://www.auanet.org/meetings-and-education/for-medical-students/medical-students-curriculum/urologic-emergencies
sugar
Treatment recommended for SOME patients in selected patient group
Where manual reduction is difficult applying granulated sugar to the area of edema, or wrapping a glucose-soaked gauze around the penis for 10 to 20 minutes before attempted manual reduction, may help extract some of the edema by osmosis.[56]Cahill D, Rane A. Reduction of paraphimosis with granulated sugar. BJU Int. 1999 Feb;83(3):362. http://www.ncbi.nlm.nih.gov/pubmed/10375281?tool=bestpractice.com Note that in some cases topical administration of granulated sugar may take 1 to 2 hours to be effective.[53]Little B, White M. Treatment options for paraphimosis. Int J Clin Pract. 2005 May;59(5):591-3. http://www.ncbi.nlm.nih.gov/pubmed/15857356?tool=bestpractice.com [57]Kerwat R, Shandall A, Stephenson B. Reduction of paraphimosis with granulated sugar. Br J Urol. 1998 Nov;82(5):755. http://www.ncbi.nlm.nih.gov/pubmed/9839597?tool=bestpractice.com
needle puncture
Needle puncture may be employed if paraphimosis cannot be treated with more conservative measures.[52]British Association of Paediatric Surgeons. Management of foreskin conditions. Jun 2006 [internet publication]. https://www.baps.org.uk/resources/management-foreskin-conditions Pressure is applied following needle puncture to facilitate reduction of edema before manual reduction is attempted.[58]Reynard JM, Barua JM. Reduction of paraphimosis the simple way - the Dundee technique. BJU Int. 1999 May;83(7):859-60. http://www.ncbi.nlm.nih.gov/pubmed/10368214?tool=bestpractice.com
The penis is sterilely prepped and a 26-gauge needle is used to make multiple (about 20) punctures in the edematous ring of foreskin.
hyaluronidase
Treatment recommended for SOME patients in selected patient group
Injection of hyaluronidase into the edematous tissue may break down hyaluronic acid and its subsequent osmotic gradient.[52]British Association of Paediatric Surgeons. Management of foreskin conditions. Jun 2006 [internet publication]. https://www.baps.org.uk/resources/management-foreskin-conditions [59]Litzky GM. Reduction of paraphimosis with hyaluronidase. Urology. 1997 Feb;50(3):160. http://www.ncbi.nlm.nih.gov/pubmed/9218042?tool=bestpractice.com Hyaluronidase may be used to augment the puncture technique.
Induces osmotic diuresis with movement of hyaluronic acid from edematous tissue.
Primary options
hyaluronidase: consult specialist for guidance on dose
compression wrap
Wrapping the phallus with a tight bandage may help to reduce edema. One technique utilizes a flexible, self-adhering bandage, which is left for 20 minutes before being removed.[60]Pohlman GD, Phillips JM, Wilcox DT. Simple method of paraphimosis reduction revisited: point of technique and review of the literature. J Pediatr Urol. 2013 Feb;9(1):104-7. https://www.jpurol.com/article/S1477-5131(12)00170-2/fulltext http://www.ncbi.nlm.nih.gov/pubmed/22827972?tool=bestpractice.com
Autoreduction of the foreskin has been reported, but manual reduction may be required when the compression wrap is removed.
preputial surgery
If conservative measures fail, definitive management in terms of either dorsal slit or circumcision may be performed.[33]Choe JM. Paraphimosis: current treatment options. Am Fam Physician. 2000 Dec 15;62(12):2623-6, 2628. http://www.aafp.org/afp/2000/1215/p2623.html http://www.ncbi.nlm.nih.gov/pubmed/11142469?tool=bestpractice.com
hypospadias
specialist referral
Although some minor forms of hypospadias do not require surgical intervention, infants with hypospadias should be referred to a specialist for further evaluation to determine the severity of the condition.
If surgical repair is desired, this can be performed in most patients on an outpatient basis as early as 3 months of age.[61]Bush NC, Holzer M, Zhang S, et al. Age does not impact risk for urethroplasty complications after tubularized incised plate repair of hypospadias in prepubertal boys. J Pediatr Urol. 2013 Jun;9(3):252-6. http://www.ncbi.nlm.nih.gov/pubmed/22542204?tool=bestpractice.com
The patient may need a postoperative urethral stent for up to 2 weeks after surgery depending upon the complexity of the repair. Boys with an incomplete prepuce should not undergo circumcision in the neonatal period and should instead be referred to a specialist. The foreskin can be reconstructed or a circumcision can be performed at the time of urethroplasty with similar outcomes in distal hypospadias.[62]Snodgrass W, Dajusta D, Villanueva C, et al. Foreskin reconstruction does not increase urethroplasty or skin complications after distal TIP hypospadias repair. J Pediatr Urol. 2013 Aug;9(4):401-6. http://www.ncbi.nlm.nih.gov/pubmed/22854388?tool=bestpractice.com
If megameatus with intact prepuce (a mild variant of distal hypospadias) is discovered during routine neonatal circumcision, the circumcision should be completed and the patient referred electively for urologic evaluation thereafter.[63]Snodgrass WT, Khavari R. Prior circumcision does not complicate repair of hypospadias with an intact prepuce. J Urol. 2006 Jul;176(1):296-8. http://www.ncbi.nlm.nih.gov/pubmed/16753427?tool=bestpractice.com
Not all patients with hypospadias will benefit from preoperative administration of topical estrogen or testosterone, and use of topical corticosteroids should be considered for each individual patient.[64]Godlewski KF, Mittal S, Hyacinthe N, et al. Does preoperative testosterone administration decrease complications in distal hypospadias repair with urethroplasty? J Urol. 2023 Aug;210(2):352-9. http://www.ncbi.nlm.nih.gov/pubmed/37195856?tool=bestpractice.com [65]Thanneeru SK, Gupta A, Chanchlani R, et al.

congenital penile curvature and/or torsion
surgery
Surgery to straighten the penis should be offered for congenital penile curvature >30 degrees or torsion >90 degrees. This can be done in conjunction with a circumcision or with foreskin preservation.
Surgery for curvature can be deferred until after puberty.[68]European Association of Urology. EAU guidelines on sexual and reproductive health. Apr 2024 [internet publication]. https://uroweb.org/guidelines/sexual-and-reproductive-health/chapter/penile-curvature
concealed penis <3 years old (before toilet training)
observation
Need for, and timing of, management for concealed penis remains controversial. Although some advocate early intervention, most pediatric urologists feel that observation may be warranted up until the age of toilet training (2-3 years of age).[1]Radhakrishnan J, Razzaq A, Manickam K, et al. Concealed penis. Pediatr Surg Int. 2002 Dec;18(8):668-72. http://www.ncbi.nlm.nih.gov/pubmed/12598960?tool=bestpractice.com [69]Borsellino A, Spagnoli A, Vallasciani S, et al. Surgical approach to concealed penis: technical refinements and outcome. Urology. 2007 Jun;69(6):1195-8. http://www.ncbi.nlm.nih.gov/pubmed/17572214?tool=bestpractice.com In this age group, redistribution of body fat often leads to spontaneous resolution of the buried penis.
phalloplasty
Treatment recommended for SOME patients in selected patient group
Urologic surgical options are available where weight loss fails to improve concealed penis. In cases of congenital concealed penis (congenital megaprepuce) that are associated with an excess of inner preputial skin with a relative paucity of shaft skin, surgical intervention is warranted at an earlier date. [Figure caption and citation for the preceding image starts]: Congenital buried penisFrom the collection of Nicol Corbin Bush, MD [Citation ends].[Figure caption and citation for the preceding image starts]: Congenital buried penis: abundant inner preputial skin with paucity of shaft skinFrom the collection of Nicol Corbin Bush, MD [Citation ends].

[Figure caption and citation for the preceding image starts]: Repaired congenital buried penis (with bilateral hernia repair and scrotoplasty)From the collection of Warren T. Snodgrass, MD [Citation ends].
In cases of concealed penis related to trauma or postoperative scarring, surgery is also indicated.
concealed penis ≥3 years old (after toilet training)
weight loss
Boys will have difficulty with a concealed penis as toilet training begins. Weight loss is the primary treatment for concealed penis.
Older boys and adults with concealed penis are unlikely to have spontaneous resolution. Weight loss is recommended primarily, with urologic surgical options also available. Although weight loss may help in adolescents and adults, the psychological impact of the condition and the low rate of improvement may warrant surgical referral.
phalloplasty
Urologic surgical options are available where weight loss fails to improve concealed penis.
Although weight loss may help in adolescents and adults, the psychological impact of the condition and the low rate of improvement may warrant surgical referral. Several operative techniques have been described, although treatment preferences vary among patient populations and surgeons.[1]Radhakrishnan J, Razzaq A, Manickam K, et al. Concealed penis.

phalloplasty
Surgical techniques vary widely among different patient populations and surgeons.[59]Litzky GM. Reduction of paraphimosis with hyaluronidase. Urology. 1997 Feb;50(3):160. http://www.ncbi.nlm.nih.gov/pubmed/9218042?tool=bestpractice.com
In patients who have undergone prior circumcision and have a paucity of penile shaft skin, skin grafting may be necessary for complete penile coverage.
micropenis
endocrine evaluation
In true cases of micropenis (stretched penile length that is 2.5 or more standard deviations less than the mean for age), endocrine evaluation by a specialist is recommended.[45]Hatipoğlu N, Kurtoğlu S.
