Giant Midline Prostatic Cyst: An Unusual Cause of Acute Urinary Retention.

Midline prostatic cysts are infrequent and mostly asymptomatic. We presented a striking case of a giant midline cyst and detailed its diagnosis, evolution, and treatment. From this case, we offered a comparison of congenital intraprostatic midline cysts, namely, Müller's cysts and utricle cysts. A 40-year-old male experienced recurrent urinary retention. A 10 × 11 mm2 cyst in the mid-prostatic region was diagnosed through transrectal ultrasound, leading to a transperineal puncture as a minimally invasive intervention. Seven years later, the cyst recurred, manifesting obstructive symptoms such as a weak urinary stream, frequent urination, and residual urine sensation. Laparoscopic surgery was then performed for the confirmed 98 × 13 mm2 cystic recurrence. The postoperative course was favourable with no complications. Symptoms were completely resolved, which was maintained over a three-year follow-up period. The therapeutic approach to midline cysts targets symptomatic cases or infertility, ranging from cyst puncture to transurethral endoscopic treatment. Recurrence after minimally invasive interventions is a challenge, with laparoscopic surgery as an alternative post-failed conservative approach. Although total cyst removal risks adjacent structure damage, marsupialisation improves the clinical outcomes. In summary, symptomatic midline prostatic cysts present challenges owing to recurrences after minimally invasive approaches. Enhanced laparoscopic techniques offer a solution, particularly in highly symptomatic cases requiring definitive treatment, as illustrated by this outstanding case report.

[A Case of Massive Prostate Abscess Treated by Transperineal Drainage].

The patient was an 81-year-old man who visited a clinic for fever and lower abdominal pain. He was subsequently diagnosed with prostatitis based on computed tomography (CT) findings that showed swelling of the prostate. Despite treatment with antibacterial therapy, his symptoms did not improve significantly. Since the patient also had myelodysplastic syndrome, he was transferred to our hospital and subsequently diagnosed with prostate abscess based on findings on magnetic resonance imaging (MRI). The abscess had spread widely from the dorsal side of the trigone of the bladder to anterior wall of the rectum. Transperineal drainage was performed to preserve the urethral mucosa of the prostatic urethra. Considering the shape of the abscess cavity, one pigtail catheter was placed in the prostate and another was placed transperineally on the dorsal side of the trigone of the bladder. Cystostomy was performed at the same time. Culture of the abscess revealed the presence of Staphylococcus aureus. As there was little exudate from the abscess 9 days after drainage, the pigtail catheter on the dorsal side of the trigone of the bladder was removed following an injection of minocycline into the abscess. CT showed shrinkage of the abscess 4 days later, and the remaining intraprostatic pigtail catheter was removed after an injection of minocycline. The cystostomy pigtail catheter was subsequently removed since the patient was able to urinate smoothly after clamping. MRI confirmed the disappearance of the abscess cavity 2 months later.

Localization of external urethral orifice in coronary sulcus during urethroplasty in case of severe hypospadias accompanied by prostatic utricle cyst.

BACKGROUND: To explore whether opening the external urethral orifice in the coronal sulcus can reduce the incidence of epididymitis after operating on hypospadias with prostatic utricle cyst (PUC) connecting to the vas deferens. Group A consisted of 3 patients with severe hypospadias and PUC undergoing cystostomy, hypospadias correction and urethroplasty, along with the relocation of the external orifice of the urethra to the coronal sulcus. Group B consisted of 4 patients having initial hypospadias repaired with meatus in the orthotopic position in the glans, presenting with multiple epididymitis after hypospadias surgery and unsuccessful conservative treatment. MR confirmed that all the Group B patients had PUC connecting to the vas deferens. Group B patients underwent urethral dilatation along with urethral catheterization, cutting of the original corpus cavernosum that encapsulated the urethra, and extension of the position of the external urethral orifice to the coronal sulcus. RESULTS: In group A, 3 children underwent bladder fistula removal 2 weeks after the operation. The penis developed normally without any complications. Four children in group B underwent stent removal 12 weeks after operation, and one patient was still stenosed and dilated again. All patients in group B were followed without epididymitis recurrence. CONCLUSIONS: For patients with hypospadias complicating with a PUC, connecting to one side of the vas deferens, the positioning of the external urethral orifice in the coronary sulcus would be helpful to reduce the occurrence of epididymitis.

[Mucinous Adenocarcinoma of the Prostate Diagnosed after Transurethral Treatment of a Prostatic Abscess].

A 70-year-old man visited his doctor because of hip pain and gross hematuria. Digital rectal examination and computed tomography revealed a prostatic abscess. Although antibiotics were prescribed, his symptoms did not improve; he was transferred to our hospital, where transurethral fenestration of the prostatic abscess was performed. During prostatic fenestration, a papillary mucous membrane was confirmed inside the cavity of the prostatic abscess. Pathological examination revealed a mucinous adenocarcinoma of the prostate. Although hormonal therapy was administered, magnetic resonance imaging revealed tumor extension necessitating robot-assisted radical prostatectomy. Mucinous adenocarcinoma of the prostate is rare, and to our knowledge this is the first report of mucinous adenocarcinoma of the prostate diagnosed after transurethral treatment of a prostatic abscess.

Surgical treatment and outcome of sterile prostatic cysts in dogs.

OBJECTIVE: To describe the surgical treatment and outcome of a large cohort of dogs with sterile prostatic cysts (PCs). STUDY DESIGN: Retrospective study. ANIMALS: Forty-four client-owned dogs. METHODS: Dogs with sterile PCs with at least 6 months of follow-up were included. Clinical variables, type of surgery, complications, recurrences, and outcomes (telephonic interviews or rechecks) were recorded. RESULTS: Extra- and intraparenchymal cysts were diagnosed in 29 and 11 dogs, respectively. Four dogs had both types. Extraparenchymal cysts were treated by partial resection and omentalization (n = 22) and complete resection (n = 7). Drainage and intracapsular omentalization were performed in all dogs with intraparenchymal cysts. The four dogs with both types of cyst were treated by omentalization. Resolution was documented in 39/44 dogs (88.6%). Intraoperative complications occurred in one dog (urethral tear). Major complications resulting in death occurred in three dogs (oliguric kidney injury, cardiac arrhythmia, and persisting urinary tract obstruction). Minor complications (n = 10) consisted of temporary urinary incontinence (n = 2), permanent urinary incontinence (n = 5), urinary retention (n = 2), and dysuria (n = 1). Recurrence occurred in two dogs with extraparenchymal cysts. Median long-term follow-up was 528 days (range, 250-730 days). Thirty-nine dogs had no signs associated with prostatic disease at long-term follow-up. CONCLUSION: Partial or complete resection and/or omentalization of sterile PCs led to resolution of clinical signs in most dogs, although postoperative urinary incontinence was frequent. IMPACT: This study is the largest case series relative to canine sterile PCs treated surgically and provides evidence on the prognosis and rate of complications.

Salvage Enbloc Thulium Fiber Laser Enucleation of Prostate for Giant Prostatomegaly After Prostatic Urethral Lift.

OBJECTIVE: To demonstrate technique of salvage thylium fiber laser enucleation of prostate in men with history of prior prostatic urethral lift (PUL) implant. PUL is an accepted treatment modality for benign prostatic hyperplasia (BPH) and is currently recommended for surgical management of prostates <80 g in size.1 However, in reality some patients with prostate >80 g also receive PUL.2 A substantial number of these patients may requirement re-treatment for recurrent or persistent lower urinary tract symptoms after PUL.3-5 Patients with larger prostates who fail PUL might be better managed with endoscopic enucleation which is a size-independent modality for treatment of BPH.1,6 Endoscopic enucleation can be accomplished via a variety of energy sources. Thulium fiber laser is a new addition to urologist armamentarium for endoscopic enucleation of prostate. We hereby present a video demonstrating salvage thulium fiber laser enucleation of 198 cc prostate in a men with history of prior PUL. METHODS: A 66-year-old male presented with a history of recurrent urine retention after prior PUL done 2 years prior at an outside institution. Pre-operative international prostate symptom score was 13, maximum uroflow rate was 6.1 ml/sec, residual urine was 26 ml despite maximal medical management. MRI demonstrated a 198 g prostate and PSA was 13.4 ng/dl with negative prostate biopsy. After a detailed discussion of options, he elected endoscopic enucleation. We employed a 550-micron Soltive superpulsed laser fiber set at 2 J and 30 Hz to perform en-bloc enucleation of prostate, and morcellation was performed with the VersaCut Morcellator. We edited the video to demonstrate the technical nuances of this procedure. RESULTS: Surgery was uneventful with enucleation time of 70 minutes and morcellation time of 142 minutes. Implants encountered during enucleation were easily separated with the thulium fiber laser. No attempt was made to remove implants segments extending beyond the plane of enucleation. Morcellation was challenging, with evidence of damage to morcellation probes requiring replacement of 3 morcellator probes. The patient was discharged on post-operative day one after successful voiding trial. At six-week follow up, his international prostate symptom score of 3 with maximum urinary flow rate of 50 mL/sec. He reported no urinary incontinence and his pathology demonstrated BPH. CONCLUSION: This video demonstrates the feasibility of thulium fiber laser enucleation of prostate after PUL, however the findings need to be reproduced in cohort studies. It also demonstrates difficulties encountered during morcellation. For smaller prostates, vaporization may be preferable, thereby avoiding difficulties associated with morcellation.

Transurethral resection of prostatic abscess.

Prostate abscess (PA) is an uncommon prostatic infection, with risk factors including indwelling catheters, acute or chronic prostatitis, bladder outlet obstruction, voiding dysfunction, recent urologic instrumentation (especially transrectal prostate biopsy), chronic kidney disease (CKD), diabetes mellitus (DM), human immunodeficiency virus (HIV), intravenous drug use (IVDU), and hepatitis C. Treatment of PA consists of antibiotics and abscess drainage via transurethral resection (TUR) or image-guided transrectal or transperineal drainage. Numerous studies have demonstrated that TUR of PA has a higher success rate and shorter hospital length of stay when compared to image-guided drainage. Despite this, TUR of PA is a relatively uncommon surgery with few useful recommendations on how to best perform this procedure. We demonstrate the TUR surgical technique for drainage of a 6 cm loculated PA in a 44-year-old man with active IVDU and hepatitis C. The patient presented with progressive voiding symptoms, urinary retention, and leukocytosis. Given the size, loculated nature of the abscess, and its proximity to the prostatic urethra, we decided to proceed to the operating room for surgical drainage as opposed to image-guided transrectal drainage. Herein we describe the trans urethral technique. He clinically improved postoperatively and repeat imaging 4 days later showed decreased abscess size. Transurethral drainage of a PA is a safe, efficient, and effective treatment option. Treatment approach should depend on abscess size, location, and presence of loculations. Combining different endourologic techniques and instruments may be necessary.

[Treatment of patients with abscess of prostate gland by the method of percutaneous punction].

OBJECTIVES: Demonstrate the treatment of prostatic abscess with a minimally invasive method - abscess puncture with aspiration of purulent fluid and injection of an antibiotic into abscess cavity. MATERIALS AND METHODS: Diagnosis of prostatic abscess of 23 patients using ultrasonography, computed tomography and magnetic resonance imaging of the pelvic region. 19 patients with the abscess within the prostatic capsule were treated with perineal percutaneous puncture method with aspiration of the abscess fluid and injection of antibiotics into cavity. For 4 patients with prostatic abscess and purulent paraprostatitis we performed incision and drainage of purulent cavity with open transperineal access. RESULTS: Single abscess puncture was enough to normalize health status of 15 patients. In 4 cases additional puncture was required in 4-5 days after the first manipulation. All the patients recovered and were discharged from the clinic in 7-8 days. Patients after abscess incision and drainage stayed in hospital for 10-14 days. In 1-3 months after the surgery, imaging methods revealed a high-density lesion in prostate whatever the method was used. DISCUSSION: Treatment response was controlled by imaging methods. 2 days after puncture 4 patients had a lesion with liquid content larger than 50% of the initial purulent lesion size. Repeated puncture was performed in this patients. CONCLUSION: Abscess puncture with aspiration of fluid is an effective method of treatment when prostatic abscess is within the capsule. In cases of purulent paraprostetitis incision and drainage of an abscess cavity is needed.

Surgical treatment for prostatic utricle cyst in children: A single-center report of 15 patients.

OBJECTIVES: To report our single-center experience of the management of children with prostatic utricle cysts. METHODS: We retrospectively analyzed 15 children who were incidentally found to have a prostatic utricle cyst and were admitted to our department between October 2013 and August 2020. Clinical characteristics and management were collected and catalogued. RESULTS: Recurrent genitourinary tract infections were the most frequent complaint, and two-thirds of patients also had hypospadias. A connection between the posterior urethra and the prostatic utricle cyst was found in all cases. Two patients directly had their progressively enlarging prostatic utricle cyst resected laparoscopically. Endoscopic techniques were used in 13 patients, two of whom underwent laparoscopic excision for repeated symptoms. The mean (range) follow-up period was 34.9 (2-82) months. No recurrences were observed in four patients who underwent prostatic utricle cyst excision and eight patients who received endoscopic treatment. Three patients had recurrent symptoms after endoscopic treatment and were managed by nonsurgical treatment. CONCLUSIONS: Prostatic utricle cyst is a rare disease which can cause recurrent genitourinary tract infections. Extra attention should be paid to evaluation for prostatic utricle cyst in children with external genital anomalies. Retrograde urethrogram and magnetic resonance imaging are useful tools with which to distinguish prostatic utricle cyst from other cystic lesions that are located in the midline pelvis in male patients. Individualized treatment is appropriate when considering fertility preservation, recurrences and malignancy. Laparoscopic excision is feasible for symptomatic and large prostatic utricle cyst. Regular long-term monitoring is recommended for all patients with prostatic utricle cyst.

Clinical Trial Protocol for LuTectomy: A Single-arm Study of the Dosimetry, Safety, and Potential Benefit of 177Lu-PSMA-617 Prior to Prostatectomy.

LuTectomy is an open-label phase 1/2 nonrandomised clinical trial evaluating the dosimetry, efficacy, and toxicity of the lutetium-177-radiolabelled small molecule PSMA-617 in men with high-risk localised/locoregional advanced prostate cancer with high prostate-specific membrane antigen expression who are undergoing radical prostatectomy and pelvic lymph node dissection.

A review of thulium-fiber laser in stone lithotripsy and soft tissue surgery.

PURPOSE OF REVIEW: To evaluate emerging evidence and practical applications of thulium-fiber laser (TFL) for genitourinary soft tissue disease and urinary stone disease treatment. RECENT FINDINGS: A systematic review was developed using the PubMed, ScienceDirect, Wiley, SpringerLink and Mary Ann Liebert Scopus databases between 2012 and 2020 years, using the PRISMA statement. We analyzed recent publications including in vitro and in humans outcomes of surgery using TFL. This new laser technology can be used in soft tissue diseases and stones present in the genitourinary system. Most of the comparisons are made with the Ho:YAG laser, using completely different settings. Nevertheless, TFL is safe, feasible and effective in the management of urologic diseases, showing superiority to Ho:YAG even in some studies. SUMMARY: The introduction of pulsed TFL technology has enabled the ablation of stones at rates comparable to or better than currently existing lasers in vitro, while also potentially reducing stone retropulsion. TFL is effective in treating genitourinary soft tissue diseases, including benign prostatic hyperplasia, and early data indicate that it may be effective in the treatment of urinary stone disease. More clinical studies are needed to better understand the indications for this novel technology and clarify its position in the urologic endoscopy armamentarium.

Single-stage Simultaneous Retrograde and Antegrade Endoscopic Treatment of Giant Prostatic and Bladder Urethral Calculi.

INTRODUCTION: Calculi encountered in the lower urinary tract typically reside within the bladder, less often in the urethra. In this video, we present a minimally invasive endoscopic approach for removal of the largest total stone volume in the lower urinary tract reported in the literature to date. METHODS: A 25-year-old male (body mass index 61 kg/m2) with neurogenic bladder presented with urosepsis and acute kidney injury secondary to obstructive uropathy. Computerized tomography (CT) of the abdomen and pelvis demonstrated bilateral severe hydroureteronephrosis, a 4.2-cm bladder stone, and 3 urethral stones, including a 7.7-cm prostatic urethral stone and 2 membranous urethral stones (Fig. 1). Urgent bilateral percutaneous nephrostomy tubes were placed. The patient elected for endoscopic management. RESULTS: The patient was placed in the supine lithotomy position. His buried penis and narrow urethra only accommodated a 16-French flexible cystoscope. Multiple stones were encountered in the membranous urethra. A 60-W SuperPulse Thulium Fiber laser at 2 J and 30 Hz was utilized to dust the urethral stones efficiently. Simultaneous ultrasound-guided percutaneous access into the bladder was obtained and ultrasonic lithotripsy via shockpulse was used to clear the bladder stone and prostatic stone from above. Total stone treatment time was 240 minutes. Suprapubic and urethral catheters were placed at the conclusion. Postoperative day 1 CT scan confirmed stone-free status and he was discharged postoperative day 2. Outpatient nephrostogram demonstrated patency of bilateral ureters and nephrostomy tubes were removed. CONCLUSION: Higher morbidity procedures including open or laparoscopic approaches have been described for management of large lower urinary tract stones. In this video, we demonstrate a minimally invasive approach of combined simultaneous antegrade and retrograde lithotripsy to achieve a stone-free status in this morbidly obese and complicated patient.

Serum paraoxonase 1 and 3 activities in benign and malignant diseases of the prostate and changes in levels following robotic-assisted laparoscopic radical prostatectomy

Background/aim: This study aimed to examine serum paraoxonase 1 and 3 (PON1 and PON3) activities in benign and malignant diseases of the prostate, to determine lipid profile and malondialdehyde (MDA) levels, and to investigate changes in levels following robotic-assisted laparoscopic radical prostatectomy (RALRP). Materials and methods: A total of 137 patients, including a control group, were enrolled in the study and assigned into four groups. Group 1 (n = 33) consisted of patients previously undergoing RALRP with no recurrence, group 2 (n = 36) consisted of patients diagnosed with prostate cancer (PCa) and undergoing RALRP, and group 3 (n = 34) consisted of patients diagnosed with benign prostatic hyperplasia. The control group (n = 34) consisted of healthy individuals. Serum low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride, cholesterol, prostate-specific antigen (PSA), PON1, PON3, and MDA values were measured. In addition, group 2 MDA, PON1, PON3, and PON1/HDL levels were investigated preoperatively and at the first month postoperatively. Results: Significant changes were found in PON1, PON3, and MDA levels. PON1 and PON3 levels decreased significantly in patients with PCa, while MDA levels increased. PON1 and PON3 increased postoperatively in the PCa group, while MDA decreased. BPH group PON1, PON3, and MDA levels were higher than those of the control group. Conclusion: An increase in free oxygen radicals in the body or a decrease in endogenous antioxidant enzyme levels can result in malignant and benign diseases of the prostate. Surgical excision of malignant tissue in PCa causes a decrease in oxidative stress.

MRI-guided, transrectal, intraprostatic steam application as potential focal therapeutic modality for prostatic diseases in a large animal translational model: A feasibility follow-up study.

Parallel to establishment of diagnostic surveillance protocols for detection of prostatic diseases, novel treatment strategies should be developed. The aim of the present study is to evaluate the feasibility and possible side effects of transrectal, MRI-targeted intraprostatic steam application in dogs as an established large animal translational model for prostatic diseases in humans. Twelve healthy experimental, intact, male beagle dogs without evidence of prostatic pathology were recruited. An initial MRI examination was performed, and MRI-targeted steam was applied intraprostatically immediately thereafter. Serum levels of C-reactive protein (CRP), clinical and ultrasonographic examinations were performed periodically following the procedure to assess treatment effect. Four weeks after treatment, all dogs underwent follow-up MRI examinations and three needle-core biopsies were obtained from each prostatic lobe. Descriptive statistics were performed. MRI-guided intraprostatic steam application was successfully performed in the study population. The first day after steam application, 7/12 dogs had minimal signs of discomfort (grade 1/24 evaluated with the short-form Glasgow Composite Measure Pain Scale) and no dogs showed any sign of discomfort by day 6. CRP elevations were detected in 9/12 dogs during the first week post steam application. Mild to moderate T2 hyperintense intraparenchymal lesions were identified during follow-up MRI in 11/12 dogs four weeks post procedure. Ten of these lesions enhanced mild to moderately after contrast administration. Coagulative necrosis or associated chronic inflammatory response was detected in 80.6% (58/72) of the samples obtained. MRI-targeted intraprostatic steam application is a feasible technique and displays minimal side effects in healthy dogs as translational model for human prostatic diseases. This opens the possibility of minimally invasive novel treatment strategies for intraprostatic lesions.

Impact of radiological diagnostics in the survivor of disseminated Fournier gangrene patient with septic pulmonary embolism.

A 51-year-old diabetic man diagnosed with prostatic abscess underwent its drainage twice. Following surgery he developed fever and right-sided painless visual loss due to endophthalmitis. To rule out its endogenous source CT scan was done which showed multisystem aetiology and complications. His pelvic CT and CT cystogram revealed postsurgical urethral injury along with urinary extravasation, perineal and pelvic soft tissues air densities with fat stranding ascribed to Fournier gangrene, air in distended urinary bladder due to emphysematous cystitis and right common iliac vein air containing septic thrombus. CT chest spotted bilateral multiple septic pulmonary emboli. These radiological findings were promptly handled by uro-surgical team followed by alliance with other relevant departments. With hasty surgical drainage/debridement, urological restoration of urinary obstruction, aggressive broad spectrum antibiotics, anticoagulation and radiological follow-ups the patient withstood multisystem lethal complications and come up with excellent outcome except evisceration.

Abscess formation following hydrogel spacer for prostate cancer radiotherapy: a rare complication.

Periprostatic abscess is a rare complication of hydrogel spacers in radiotherapy for prostate cancer. We present the case of a 61-year-old man who developed this condition. Abdominopelvis CT scan revealed a 54×35×75 mm collection in the location of the SpaceOAR, for which ultrasound-guided transperineal percutaneous drainage of the periprostatic abscess was performed. The patient remains well with serial CT scans showing near resolution of the collection.

Two-Staged Versus Three-Staged Laparoscopic Anorectoplasty for Patients with Rectoprostatic and Bladder Neck Fistulas: A Comparative Study.

Purpose: To compare the results of two- versus three-staged laparoscopic anorectoplasty (LARP) in children with rectoprostatic and bladder neck fistulas. Materials and Methods: The present study was retrospectively initiated among 32 consecutive patients who underwent two-staged LARP from October 2010 to December 2012. The associated defects, age at the operation, operative time, complications, length of the postoperative hospital stay, total hospitalization cost, and functional results (according to the Krickenbeck scoring system) were evaluated. The results were compared with those of 19 cases who underwent three-staged LARP from October 2008 to September 2010. Results: The average age at the second operation was 4.5 ± 1.2 months in the two-staged group, and 4.2 ± 1.3 months in the three-staged group. In the two-staged group, there were statistically shorter overall operative time and postoperative hospital stay duration. Also, a significantly lower total hospitalization cost was achieved. There was no anastomotic leak in either group. The rates of perineal wound infection, recurrent fistula, and rectal prolapse were 3.85% versus 0% (P = 1.000), 0% versus 5.3% (P = .422), and 11.5% versus 15.8% (P = .686), respectively (two-staged versus three-staged group). The median follow-up time was 67 (range, 54-80) months and 88 (range, 81-104) months, respectively. No significant difference in functional outcome was observed. Conclusions: Two-staged LARP is feasible, safe, and more cost-effective, with comparable incidences of complications and functional outcomes with respect to a three-staged procedure.

Robotic-assisted Excision of Giant Prostatic Utricular Cysts: Technique, Outcomes and Follow-up.

BACKGROUND: Utricular cysts are usually the result of incomplete involution of the Müllerian ducts and may have no urethral connection. Treatment options for symptomatic utricular cysts include an open abdominal approach, trans-vesical excision, vasoligation without excision and laparoscopic/robotic-assisted excision. PATIENTS AND METHODS: Two patients (14 and 45 years old) with recurrent urinary tract infections associated with recurrent lower urinary tract irritative symptoms and recurrent perineal pains presented to our department. Clinical, radiological and MRI examinations showed 6x3 and 5x4cm utricular cysts, respectively. Both patients underwent robotic-assisted complete dissection of the cyst, including its neck. Separation of the cysts from surrounding tissues as well as the seminal vesicles while avoiding injury to the neurovascular bundles was followed by incision of the prostate base to dissect the cyst neck from the prostatic parenchyma up to its connection to the urethra. The cyst neck was secured with either one clip or 4/0 vicryl sutures. The field was reconstructed with 4/0 sutures. The patients were followed-up at 3, 6 and 12 months postoperatively. RESULTS: There were no intraoperative complications or injuries to the neighboring structures (seminal vesicles, vas deferens and urethra). The operative time was 95 and 80 minutes, respectively, with negligible blood loss. Both patients underwent an uneventful recovery from surgery, and were discharged on the 5th postoperative day. Both patients were asymptomatic throughout the entire follow-up period (15 months). MRI at 3 months showed no abnormalities. The postoperative IIEF score in the older patient showed no difference compared to his baseline findings. The life quality score showed high patient acceptance and both patients indicated that they would recommend the procedure. CONCLUSIONS: Symptomatic presentation of utricular cysts may be associated with recurrent urinary tract infections, orchitis-epididymitis and potential for malignancy. The present cases demonstrate that robotic-assisted surgical excision of symptomatic utricular cysts is a feasible and safe procedure. It seems to provide excellent visualization and access to these lesions. This procedure provides patients the advantages of minimally invasive surgery with outcomes comparable to those with other management techniques.

Population-based assessment of re-treatment and healthcare utilisation after photoselective vaporisation of the prostate or electrosurgical transurethral resection of the prostate.

OBJECTIVE: To compare the healthcare utilisation and repeat surgical treatment rate amongst older men undergoing an electrosurgical-transurethral resection of the prostate (TURP) vs photoselective vaporisation of the prostate (PVP), as the real-world implementation and outcomes of laser-based treatment have not been well studied. PATIENTS AND METHODS: We used administrative data from the province of Ontario, Canada, to identify all men aged >66 years who underwent their first electrosurgical-TURP/PVP between 2003 and 2016. Our primary exposure was type of procedure (PVP or electrosurgical-TURP). Our primary outcome was need for repeat surgical treatment. The primary analysis was an adjusted marginal Cox model approach, which accounted for clustering of patients within surgeons; adjusted hazard ratios (aHRs) or odds ratios (aORs) and 95% confidence intervals (CIs) are reported. RESULTS: We identified 52 748 men: 6838 (13%) underwent PVP, and 45 910 (87%) underwent electrosurgical-TURP. The median age was similar, and PVP became more common with time. Compared to the PVP group, more patients in the electrosurgical-TURP group had prior gross haematuria or urinary retention, and fewer had used anticoagulants, α-blockers, or 5α-reductase inhibitors. The need for repeat surgical treatment was significantly higher amongst men who had PVP (aHR 1.57, 95% CI 1.38-1.78; absolute risk difference +2.3%). PVP was also associated with a slightly higher risk of return to the emergency room within 30 days (aOR 1.11, 95% CI 1.01-1.22) and a significantly lower risk of blood transfusion (aOR 0.24, CI 0.16-0.37); the majority of PVP cases were done with a <24 h stay (73%) vs electrosurgical-TURP (7%). CONCLUSIONS: While some of the expected benefits of PVP (such as reduced transfusion risk and shorter length of stay) were observed, the significantly higher rate of repeat surgical treatment compared to electrosurgical-TURP may represent an important difference in implementation of this technology outside of clinical trials.
