Background: Keloids can occur anywhere in the human body. They are difficult to remove and can cause distress in patients. Although many options are available to treat keloids, no single method is considered the optimal treatment of choice. The authors encountered cases where an umbilical keloid developed at the trocar site after laparoscopic surgery and managed the keloid using a transposition flap. Methods: A total of 10 umbilical keloid patients treated from 2013 to 2020 were included in this study. All patients developed a keloid due to the placement of a laparoscopic trocar incision port, and their major complaints varied from an asymptomatic nodule to pruritus or pain. All excisions were performed under local anesthesia, and transposition flaps were planned afterward. The surrounding tissue was rearranged so that the shape of the umbilicus was deformed to the minimum extent possible. The keloid scars were examined both preoperatively and 6 months postoperatively using the Patient and Observer Scar Assessment Scale (POSAS). Results: All surgical wounds healed well without complications. The average time interval from laparoscopic surgery to keloid scar revision was 4.3 years. The mean postoperative follow-up period was 10.9 months, and no patient underwent reoperation. Four patients were treated with triamcinolone after surgery due to mild hypertrophy or pruritus. The POSAS observer scale showed significantly decreasing scores over time in all patients (P=0.002). Conclusions Cosmetically unfavorable keloids that form in the umbilicus following laparoscopic surgery can be improved with a simple procedure using excision and transposition flaps.

Background: Nipple reconstruction is usually performed as a delayed procedure in patients with breast cancer who undergo skin-sparing mastectomy and breast reconstruction surgery using a deep inferior epigastric perforator (DIEP) flap. The authors designed this study to evaluate the utility of breast reconstruction based on a DIEP flap and immediate nipple reconstruction. Methods: A retrospective review was conducted of all patients who underwent breast reconstruction performed by a single plastic surgeon from October 2016 to June 2018. Through a questionnaire and chart review, we compared surgical results and complications in cases of single-stage nipple reconstruction after skin-sparing mastectomy (n=17) with patients who underwent delayed nipple reconstruction after skin-sparing mastectomy, modified radical mastectomy, or simple mastectomy (n=7). Results: In a subjective analysis using clinical photos, the immediate nipple reconstruction group had higher scores than their counterparts in an evaluation of the nipple-areolar complex (NAC) (NAC placement, 3.34 vs. 3.04; nipple projection, 3.05 vs. 3.03; nipple size, 3.30 vs. 3.29). No significant differences between the groups were found in terms of complications. Conclusions Simultaneous nipple reconstruction is a reliable surgical method with economic advantages. No differences were found in terms of outcomes and complications in comparison to delayed reconstruction. Therefore, surgeons can consider simultaneous nipple reconstruction without particular concerns about asymmetry or necrosis.

BACKGROUND: Various methods have been reported for the improvement of widened or depressed scars. However, scars can be complex at presentation. If a widened but flat portion is combined with a tethered or a depressed area, a scar revision method that can effectively resolve all issues is needed. The authors utilized a dermal portion of the widened scar as a re-adhesion barrier and filled tissue after the release of the tethering or depression. METHODS: From July 2014 to December 2017, a total of eight patients presented with combined scars with both widened and depressed areas and underwent scar revisions with scar dermal transposition flaps. The scar flap of the widened scar was de-epithelialized, leaving the dermo-cutaneous pedicle near the depressed area. Without any additional skin incision on the depressed site, the tethering was released by making a skin incision at the scar flap. The de-epithelialized scar dermal flap was transpositioned under the depressed area of the scar. RESULTS: The surgical wounds of all eight patients healed without any complications. The mean follow-up period was 5.25 months. The filling effect of the scar flap persisted without the conspicuous relapse of a depression or tethering. The patients were satisfied with the final results and the fact that no additional incision was needed for the tethered and depressed scar. CONCLUSIONS: If the depressed site is near a widened scar, a scar dermal transposition flap may be a versatile option for improving the depression without an additional skin incision.

Prostate cancer is the most common type of male cancer worldwide. Although radical prostatectomy (RP) is advised for prostate cancer in patients with a life expectancy of more than 10 years by various guidelines, most elderly men still do not undergo the procedure regardless of increasing life expectancy. This study aimed to determine whether RP is suitable for patients with prostate cancer aged 75 years or older. A retrospective study of patients who underwent RP at 6 institutions between 2005 and 2012 was conducted. Patients were divided into 2 groups at the time of surgery: 65-69 years (younger group) and 75 years or older (older group). We compared clinical characteristics, pathological results, complication rates, and recurrence-free survival between the two groups. Compared with the younger group, the older group had significantly higher preoperative serum prostate-specific antigen level, pre- and postoperative Eastern Cooperative Oncology Group (ECOG) performance status grade, hypertension prevalence, and Gleason score at biopsy and RP. However, except urinary incontinence, there were no statistically significant differences in the peri- and post-operative complications. After median follow-up periods of 36 months (younger group) and 40 months (older group), the biochemical recurrence-free survival rates were not significantly different (P = 0.581). Although the urinary incontinence rate was higher in the older group, RP was a suitable option for selected Korean men aged 75 years or older with limited complication rates and excellent outcomes similar to those for patients aged 65-69 years.

PURPOSE: The purpose of this study is to evaluate the effect of diabetes mellitus (DM) and preoperative glycemic control on prognosis in Korean patients with upper tract urothelial carcinoma (UTUC) who underwent radical nephroureterectomy (RNU). MATERIALS AND METHODS: A total of 566 patients who underwent RNU at six institutions between 2004 and 2014 were reviewed retrospectively. Kaplan-Meier and Cox regression analyses were performed to assess the association between DM, preoperative glycemic control, and recurrence-free, cancer-specific, and overall survival. RESULTS: The median follow-up period was 33.8 months (interquartile range, 41.4 months). A total of 135 patients (23.8%) had DM and 67 patients (11.8%) had poor preoperative glycemic control. Patients with poor preoperative glycemic control had significantly shorter median recurrence-free, cancer-specific, and overall survival than patients with good preoperative glycemic control and non-diabetics (all, p=0.001). In multivariable Cox regression analysis, DM with poor preoperative glycemic control showed association with worse recurrence-free survival (hazard ratio [HR], 2.26; 95% confidence interval [CI], 1.31 to 3.90; p=0.003), cancer-specific survival (HR, 2.96; 95% CI, 1.80 to 4.87; p=0.001), and overall survival (HR, 2.13; 95% CI, 1.40 to 3.22; p=0.001). CONCLUSION: Diabetic UTUC patients with poor preoperative glycemic control had significantly worse oncologic outcomes than diabetic UTUC patients with good preoperative glycemic control and non-diabetics. Further investigation is needed to elucidate the exact mechanism underlying the impact of glycemic control on UTUC treatment outcome.

PURPOSE: To evaluate the association of self-reported erectile function and endothelial function using the EndoPAT device. MATERIALS AND METHODS: We prospectively enrolled 76 men (age> or =40 years) after obtaining a complete medical history and a self-reported questionnaire (International Index of Erectile Function-5 [IIEF-5], SEP Q2, Q3). Endothelial function was noninvasively measured with an EndoPAT 2000, recorded as the reactive hyperemia index (RHI), and analyzed according to the patients' baseline characteristics. RESULTS: The mean patient age and IIEF-5 score were 62.50+/-8.56 years and 11.20+/-6.36, respectively. In comparing the RHI according to erectile dysfunction (ED) risk factors, the RHI was significantly lower in older subjects (p=0.004). There was no difference in the RHI according to age, body mass index, waist circumference, obesity, smoking habit, or other comorbidities. When the subjects were divided into four groups according to the severity of ED, no statistical differences in the RHI value were found among the groups. There was no difference in IIEF-5 according to the RHI when categorized according to the normal cutoff value or quartile ranges. The second subdomain of IIEF-5 (erection firmness) was significantly correlated with the RHI value (R=0.309, p=0.007); however, this was not the case with the other IIEF-5 subdomains. Self-assessment showed a tendency toward a negative correlation with the RHI value (R=-0.202, p=0.080). CONCLUSIONS: The role of endothelial function measurement by the EndoPAT in the evaluation and management of ED patients remains inconclusive. However, further studies are needed to validate the role of endothelial function measurement, by the EndoPAT or any other device.

PURPOSE: Transurethral resection of bladder tumor (TURBT) can be a challenging procedure for an inexperienced surgeon. We suggest an easy technique for TURBT, which we have named the "grasp and bite" technique. We describe this technique and compare its effectiveness and safety with that of conventional TURBT. MATERIALS AND METHODS: Monopolar TURBT (24-Fr Karl Storz) was performed in 35 patients who had superficial bladder tumors. After defining the tumor margin, the tumor and surrounding mucosa were grasped by use of a loop electrode and resectoscope sheath. With tight grasping, linear moving resection was performed. The patients' demographic, intraoperative, and postoperative data were analyzed between the conventional and grasp and bite TURBT groups. RESULTS: Of 35 patients, 16 patients underwent conventional TURBT (group 1), and the other 19 patients underwent grasp and bite TURBT (group 2). Both groups were similar in age, tumor multiplicity, size, anesthesia method, and location. Grasp and bite TURBT could be performed as safely and effectively as conventional TURBT. There were no significant differences in irrigation duration, urethral catheterization, postoperative hemoglobin drop, or length of hospital stay. No significant side effects such as bladder perforation, severe obturator reflex, or persistent bleeding occurred. There were no significant pathological differences between specimens according to the type of resection technique. CONCLUSIONS: The grasp and bite TURBT technique was feasible for superficial bladder tumors. It may be a good tool for inexperienced surgeons owing to its convenient and easy manner.

PURPOSE: To evaluate the prevalence of bladder neck contracture (BNC) and its risk factors in patients undergoing radical prostatectomy in Korea. MATERIALS AND METHODS: We analyzed data from 488 patients with prostatic cancer who underwent radical prostatectomy performed by seven surgeons in seven hospitals, including 365 open radical prostatectomies (ORPs), 99 laparoscopic radical prostatectomies (LRPs), and 24 robot-assisted laparoscopic radical prostatectomies (RARPs). Patients with BNCs were compared with those without BNCs to identify the risk factors for BNC occurrence. RESULTS: Overall, BNCs occurred in 21 of 488 patients (4.3%): 17 patients (4.7%) who underwent ORP, 4 patients (4%) who underwent LRP, and no patients who underwent RARP. In the univariate analysis, men with BNCs had a longer length of time before drain removal (12 days vs. 6.8 days, p<0.001), which reflected urinary leakage through the vesicourethral anastomosis. In the multivariate analysis, the length of time before drain removal was the only predictor of BNC (odds ratio, 1.12; p=0.001). Intraoperative blood loss was higher in patients with BNC, but the difference was not statistically significant. CONCLUSIONS: The most significant factor related to BNC occurrence after radical prostatectomy in our study was the length of time before drain removal, which reflects urinary leakage from the vesicourethral anastomosis. The proper formation of a watertight anastomosis to decrease urinary leakage may help to reduce the occurrence of BNC.

PURPOSE: We evaluated men with documented chronic prostatitis and elevated serum prostate-specific antigen (PSA) to determine whether treatment with antibiotics and anti-inflammatory drugs can lower serum PSA and the cancer detection rate in patients with post-treatment PSA <4 ng/ml. MATERIALS AND METHODS: Eighty-six men who presented with serum PSA greater than 4 ng/ml and who were subsequently diagnosed with chronic prostatitis with greater than 10 white blood cells per high power field in expressed prostatic excretions were included in this prospective study. Patients meeting these criteria underwent treatment with a 4-week course of antibiotics and nonsteroidal anti-inflammatory agents. Follow-up PSA and transrectal ultrasonography-guided prostate biopsy were performed within 2 months of treatment for all patients. RESULTS: Mean patient age was 56.2 years (range, 37-72 years). Mean PSA (ng/ml) decreased by 33.8%, from 8.12 (range, 4.02-24.8) to 5.37 (range, 1.35-12.94), after treatment (p=0.001). Pathological studies revealed prostate cancer in 18 cases (20.9%), chronic inflammation in 64 (74.4%), and benign prostatic hypertrophy in 4 (4.7%). The prostate cancer detection rate according to the follow-up PSA level, below 2.5, from 2.5 to 4.0, and above 4.0, was 13.3% (2/15), 13.6% (3/22), and 26.5% (13/49), respectively. CONCLUSIONS: When chronic prostatitis with elevated PSA is identified, antibiotic and anti-inflammatory treatment can lower these PSA levels. However, the possibility of prostate cancer remains in patients whose PSA level decreases to less than 4 ng/ml, even in those with a PSA level less than 2.5 ng/ml.

PURPOSE: We prospectively evaluated the surgical outcomes of single scrotal incision orchiopexy in children with a palpable undescended testis compared with the traditional two incision orchiopexy. MATERIALS AND METHODS: A total of 398 orchiopexies (292 children) were included and randomly assigned to the single scrotal incision orchiopexy group (Group I, 147 children, 201 testes) or the traditional inguinal incision orchiopexy group (Group II, 145 children, 197 testes). The final number of patients enrolled (excluding those lost to follow-up) was 107 children (146 testes) in group I and 105 children (141 testes) in group II. Success was defined as no complications, postoperative intrascrotal location of the testis, and no conversion to the traditional inguinal approach. Surgical outcomes and complications were compared between the two groups. Testicular location, complications, and subjective satisfaction rate were assessed at the follow-up evaluation at least 12 months postoperatively. RESULTS: The overall success rate in group I was 92.5% in 135 of 146 testes; the remaining 9 testes required conversion to traditional two incision orchiopexy. In group II, orchiopexy was successful in 136 of 141 testes (96.5%). The operation time and hospital stay were significantly shorter in group I (40.5+/-25.9 minutes, 2.1+/-0.8 days) than in group II (62.3+/-35.6 minutes, 2.5+/-0.7 days), respectively (p<0.001, p=0.03). Postoperative complications were found in two cases (hematoma, wound dehiscence) in group I and in one case (wound dehiscence) in group II; all cases with complications recovered with conservative care. The subjective rate of satisfaction with the cosmetic result was 96.6% in group I and 96.5% in group II (p=0.97). CONCLUSIONS: We conclude that single scrotal incision orchiopexy is a simple technique that is associated with a shorter operation time and hospital stay than the traditional method and that is more feasible cosmetically.
