Penile circumference and stretched penile length in prepubertal children: A retrospective, single-center pilot study.

Investig Clin Urol 2021 May;62(3):324-330

Department of Urology, Pusan National University Yangsan Hospital, Yangsan, Korea.

Purpose: To determine references for penile circumference according to age in prepubertal children and whether this measurement can be used as a basic penile parameter along with stretched penile length in prepubertal children.

Materials And Methods: A total of 750 children (mean age, 4.2±3.4 years) aged under 14 years without penile problems were enrolled in this study. Children with penile or testicular abnormalities were excluded. All data were gathered at the outpatient clinic by a single pediatric urologist from July 2017 to April 2020. Penile parameters (baseline and stretched penile length, penile circumference) and testicular volumes were measured by using an elastic ruler and a Prader orchidometer, respectively.

Results: Mean baseline and stretched penile lengths were 3.0±1.0 cm and 4.2±1.0 cm, respectively. The mean penile circumference was 4.2±0.9 cm. The stretched penile length was similar to penile circumference (p=0.425). This similarity was found for each age group except for the 0-1-year-old and 3-4-year-old age groups (p=0.001 and p=0.034, respectively). As children grow into adolescence, stretched penile length increases significantly compared to penile circumference.

Conclusions: Penile circumference increased with age like stretched penile length and testicular volume in prepubertal children. Stretched penile length and penile circumference were found to be similar. This study can be used as a basic reference for penile circumference values in prepubertal children.

Concealed index for concealed penis in prepubertal children.

Investig Clin Urol 2021 Mar;62(2):217-223

Department of Urology, Pusan National University Yangsan Hospital, Yangsan, Korea.

Purpose: The concealed penis (CP) is a congenital or acquired genital anomaly that requires surgical correction. To construct an objective CP severity index, we compared the penile parameters of a CP with a normal penis (NP) and postoperative outcomes of CP patients.

Materials And Methods: In this retrospective study, 391 boys under 14 years who visited our hospital between September 2017 and February 2020 were included. Among these boys, 105 patients had a CP and 286 boys had a NP without CP. The stretched penile length (SPL), penile circumference (PC), and penile length above baseline skin level (BPL) were measured using a ruler (cm), and the testicular volume was measured using an orchidometer (mL). We defined the concealed index according to SPL (CIs) as BPL/SPL and the concealed index according to circumference (CIc) as BPL/PC. A repair of the CP was performed in the CP patients. All parameters were measured before surgery and after three months.

Results: The CP had significantly shorter SPL and BPL, and smaller CIs, and CIc than the NP. The cutoff values for the CIs and CIc were 0.68 and 0.58, respectively (sensitivity 86.7% and 86.7%; specificity 65.0% and 88.5%, respectively). After repair of the CP, all penile parameters were significantly improved.

Conclusions: The CIs and CIc are useful and objective parameters for checking the severity of CP, and evaluating the postoperative outcome of CP repair. We newly introduced cutoff values for the CIs (0.68) and CIc (0.58) for diagnosing and evaluating CP repair.

Pediatric laparoscopic pyeloplasty of pelvic ectopic kidney with UPJO - A case report.

Urol Case Rep 2021 Jan 23;34:101507. Epub 2020 Nov 23.

Department of Urology, Pusan National University Yangsan Hospital, Yangsan, South Korea.

Prevalence of pelvic ectopic kidney with obstruction is not common. Associated anomalies may produce technical difficulties and surgical challenges in treatment. Diagnostic tools such as USG KUB, renal scintigraphic studies (DMSA, DTPA), MRI, and preoperative RGP are very informative examinations to properly decide the timing of the operation and method of it. The patient was under close surveillance from the detection of antenatal hydronephrosis until the development of UPJ obstruction. Herein, we report the case of a patient with this anomaly who successfully underwent laparoscopic reconstruction.
