About the Lab

Professor Gwang-Jin Ko's research lab specializes in urological surgery, with a primary focus on pelvic floor disorders, including pelvic organ prolapse (POP), interstitial cystitis, and postprostatectomy urinary incontinence. The lab investigates minimally invasive and robotic surgical techniques to improve surgical outcomes, with particular emphasis on sacrocolpopexy, male slings, and endoscopic ablation of Hunner lesions. The team also explores predictive factors for surgical success and recovery, such as surgeon experience and patient-specific anatomical scores, aiming to optimize patient care through evidence-based surgical innovation.

Current surgical management of pelvic organ prolapse: Strategies for the improvement of surgical outcomes
Kwang Jin Ko, Kyu‐Sung Lee
SJR Q1Investigative and Clinical UrologyOA

There are a variety of surgical management strategies to help surgeons repair pelvic organ prolapse (POP). Surgical treatment for POP includes native tissue repair, augmentation with mesh, and minimally invasive surgeries. Currently, laparoscopic or robotic techniques for POP repair are increasing in popularity and continuing to evolve. The aim of this review is to present an up-to-date review of surgical techniques used for POP repair and to discuss ways to optimize surgical outcomes.

OBJECTIVE: To investigate the efficacy of endoscopic ablation of Hunner lesions (HLs) in patients with interstitial cystitis (IC) and to find predictors of early recurrence of HLs. PATIENTS AND METHODS: A prospective study was performed of patients with Hunner type IC who underwent transurethral ablation. We repeated endoscopic ablation when symptoms and HLs recurred during the follow-up period. The primary endpoint was recurrence-free time. Secondary endpoints were a change in frequency, noctur

Sling Surgery for Male Urinary Incontinence Including Post Prostatectomy Incontinence: A Challenge to the Urologist
Kwang Jin Ko, Sung Jin Kim, Sung Tae Cho
SJR Q2International Neurourology JournalOA

The management of postprostatectomy urinary incontinence (PPI) is still challenging for urologists. In recent decades, various kinds of male sling system have been developed and introduced; however, they have not yet shown as good a result as that of artificial urinary sphincter (AUS). However, a male sling is still in an important position because patients have a high demand for sling implantation, and it can allow the avoidance of the use of mechanical devices like AUS. Recently, the male slin

Robotic Sacrocolpopexy for Treatment of Apical Compartment Prolapse
Kwang Jin Ko, Kyu‐Sung Lee
SJR Q2International Neurourology JournalOA

Abdominal sacrocolpopexy is the gold-standard treatment for apical compartment prolapse, as it is more effective and durable than the transvaginal approach. In the current era of minimally invasive surgery, laparoscopic sacrocolpopexy techniques have been described, but have not gained popularity due to their complexity and steep learning curves. To overcome this problem, robotic sacrocolpopexy was introduced, and has shown equivalent outcomes and safety compared to open and laparoscopic sacroco

Surgeon experience, tumor size, and PADUA score predicted prolonged WIT after RPN or LPN. Among these factors, increasing surgical experience with LPN or RPN is the most important factor for preventing prolonged WIT.

The Remeex system provided a good cure rate and improved the quality of life of women with SUI and DU. Therefore, the Remeex system should be considered as a treatment option for female patients with concomitant SUI and DU.

Clinical implications of underactive bladder
Kwang Jin Ko, Chung Un Lee, Kyu‐Sung Lee
SJR Q1Investigative and Clinical UrologyOA

Underactive bladder (UAB) is a common urologic condition but a complex disease that causes troublesome lower urinary tract symptoms. Currently, management of UAB remains unsatisfactory. Also, many urological diseases can be combined with UAB. In these combined cases, the treatment results may be affected by UAB component. This review focuses on the clinical implications of UAB in patients with common urologic conditions, including bladder outlet obstruction, overactive bladder syndrome and stres

SJR Q1Neurourology and Urodynamics

AIM: We investigated the satisfaction and efficacy of mirabegron in patients with overactive bladder (OAB) symptoms who were unsatisfied with previous antimuscarinic treatment. METHODS: This was a 12-week, open-label study of adults with OAB who had been treated with antimuscarinics within 2 years of screening and expressed dissatisfaction over poor efficacy or adverse events of antimuscarinics. All enrolled patients have received mirabegron 50 mg once daily for 12 weeks. The primary outcome was

SJR Q1Scientific ReportsOA

We performed a prospective, single-arm study comparing outcomes between transurethral ablation plus postoperative instillation of hyaluronic acid and chondroitin sulfate (HACS group) and transurethral ablation only in patients with Hunner type interstitial cystitis (historical control group). A total of 78 patients were enrolled, and 51 were included in the per-protocol analysis set. The 2-year recurrence rate was 47.1% (95% CI, 32.9-61.5) in the HACS group, which was significantly lower than th

Optimal endoscopic treatment and partial cystectomy with or without bladder augmentation for Hunner‐type interstitial cystitis

SJR Q2LUTS Lower Urinary Tract SymptomsOA

Interstitial cystitis/bladder pain syndrome (IC/BPS) presents a significant challenge for urologists in terms of management, owing to its chronic nature and adverse impact on patient quality of life. Given the potential distinction between two disease entities within IC/BPS, namely Hunner-type IC and BPS without Hunner lesion, there is a need for an optimal therapeutic approach that focuses on the bladder lesions in Hunner-type IC. In cases where Hunner lesions are observed, complete transurethr

SJR Q1International Journal of Molecular SciencesOA

Background: Hunner-type interstitial cystitis (HIC) is a chronic inflammatory condition of the bladder. However, it remains unclear whether there is a causal relationship between the presence of Hunner lesions and seemingly normal-appearing areas in the bladder (non-Hunner lesions). This study aimed to investigate the fundamental aspects of HIC by examining potential genetic differences between Hunner and non-Hunner lesions and elucidate their role as potential markers in the progression and sup
