Genitourinary vascularized composite allotransplantation for gender affirmation in trans men: An anatomical feasibility study.

PURPOSE: Gender affirmation in trans men requires multiple staged procedures. The final masculinizing step involves phalloplasty or metoidioplasty and further incorporation of penile and testicular prostheses. However, these are functionally suboptimal and associated with high complication rates. Therefore, we sought to investigate the anatomical feasibility of one-stage genitourinary vascularized composite allotransplantation (GUVCA) for such gender-affirming surgeries. METHODS: Twenty fresh cadaveric dissections were performed to delineate the neurovascular anatomy of the proposed GUVCA. Specifically, in donors (n = 14), besides the penis and scrotum, the GUVCA included an inferior bladder patch with the urinary sphincter, prostate, seminal vesicles, as well as a strip of the pubic bone. In trans men recipients, osteotomies of the pubic bone to match that of the donor GUVCA were required. Five cadaveric GUVCA transplants were then performed to simulate one-stage gender affirmation surgery. RESULTS: The GUVCA required (1) vascular anastomoses between the recipient's deep inferior epigastric, external pudendal, and superficial circumflex iliac (or superficial inferior epigastric) vessels to the donor's internal pudendal, external pudendal and genitofemoral vessels respectively; (2) neurosynthesis between the recipient pudendal and dorsal clitoral nerves to the donor pudendal and genitofemoral nerves; and (3) urinary bladder anastomosis at the bladder neck, upstream of the urinary sphincter. Average donor measurements (length (cm), diameter (mm)) were: external pudendal artery (2.5, 2.0) and vein (2.0, 3.5), internal pudendal artery (15.0, 4.0), pudendal (15.0, 3.0) and genitofemoral nerves (8.0, 2.0). CONCLUSIONS: We have described the anatomical basis for a one-stage GUVCA in trans masculine genitourinary reconstruction.

Bladder tumor Resection Weight as a Prognostic Factor for Recurrence and Progression in Patients With High-Risk Non-Muscle Invasive Bladder Treated With BCG.

INTRODUCTION: Predicting outcomes of patients with high-risk non-muscle invasive bladder cancer (HR-NMIBC) is critical. Here, we evaluate whether bladder tumor resection weight might serve as a prognostic factor for recurrence and progression of HR-NMIBC patients treated with Bacillus Calmette-Guérin (BCG). METHODS: In this retrospective, single-centre study in the UK, we analysed a consecutive cohort of HR-NMIBC patients who have received adequate intravesical BCG immunotherapy between 2009 and 2019. Univariable and multivariable Cox proportional hazards models were used to assess the association of resection weight and established predictors with recurrence and progression. RESULTS: A total of 187 HR-NMIBC patients were analysed. The median resection weight was 1.4g (range: 0.2-28.5g). Within a median follow-up of 41 months, 58 (31%) tumors recurred and 19 (10%) progressed. Fifty-four patients (29%) died from any cause and 16 (9%) died from bladder cancer. Both the risk of recurrence (P = .007) and progression (P = .019) increased with rising resection weight. On the multivariable analysis, a resection weight of ≥ 2g and ≥ 3g conferred a 4.35-fold and a 9.03-fold increased risk of bladder cancer recurrence (P < .001) and progression (P < .001), respectively. The addition of resection weight improved the C index of multivariable standard prognostic models to a clinically significant extent (+ 3.8% for recurrence, + 4.3% for progression). CONCLUSION: In our HR-NMIBC patient cohort treated with BCG, bladder tumor resection weight was associated with disease recurrence and progression. Its addition improves discrimination of standard prognostic factors. Measurement may therefore be considered for routine clinical practice.

Surgical and radiological predictive factors for ureteric stricture formation in patients treated with ureteroscopy for ureteric stones.

BACKGROUND: Ureteric stricture is a potential complication of impacted ureteric stones. This study investigates surgical and radiological factors that could predict ureteric stricture formation after ureteroscopic treatment of impacted ureteric stones. MATERIALS AND METHOD: Intraoperative and radiological data for patients who underwent ureteroscopic treatment of ureteric stones impaction over a 5-year period were reviewed retrospectively. Patients who had previous ureteroscopic treatment or strictures were excluded. RESULTS: Between January 2014 and May 2019, 1,340 patients presented as emergency renal colic secondary to ureteric stones. A total of 297 ureteroscopy procedures were performed for impacted calculi. The mean age was 53 years. The stricture rate was 3.3%. Analysis of radiological and surgical factors revealed that the degree of hydronephrosis, residual fragments and intraoperative ureteric injury were significant predictors for stricture formation (p = 0.018, 0.01 and 0.02, OR = 10, 47 and 1776, respectively). None of the other factors significantly predicted ureteric stricture formation. CONCLUSION: Our study found the presence of severe hydronephrosis, residual stone fragments after surgery and intraoperative ureteric injury are significant predictive factors for ureteric stricture formation. The high-risk patients should be monitored with routine postoperative renal ultrasound.

Dermatological manifestation of metastatic prostate cancer.

A 59-year-old man presented to the urology department with increased urinary urgency, frequency, poor urinary flow and unintentional weight loss. He had a 25-year history of idiopathic urticaria episodes which had increased in frequency over the previous 2 months. On investigation, he was found to have a raised prostate-specific antigen level. He was investigated further with a multiparametric MRI, a local anaesthetic transperineal prostate biopsy, a CT scan of chest/abdomen/pelvis with contrast and a nuclear medicine bone scan. He was diagnosed with metastatic adenocarcinoma of the prostate and commenced on a luteinising hormone-releasing hormone antagonist and referred to oncology for further treatment. Since starting treatment, he has experienced no further episodes of urticaria.

Post vasectomy chronic pain: are we under diagnosing vasitis? A case report and review of the literature.

Acute vasitis is a rare infection of the vas deferens. Clinical presentation and disease rarity can cause difficulty in correctly diagnosing this condition. Adjuncts to aid diagnosis can be used that include ultrasound scan (USS) or computed tomography. We report a unique case of acute vasitis following vasectomy, reversal and subsequent re-do vasectomy diagnosed using USS.

A case of persistent haematospermia secondary to seminal vesicle calculi in an ageing male.

Seminal Vesicle (SV) calculi are a rare pathology. Clinical presentation usually consists of nonspecific perineal pain and haematospermia. Adjuncts to aid diagnosis include US, MRI, and Vesiculography. This rare condition can be treated conservatively, however, surgical options are becoming more advanced with Vesiculoscopy now being the gold standard. Here, we present a case of a SV calculi treated conservatively.

Persistent hematospermia: seminal vesicle bleed.

A 65-year-old gentleman, with no past medical problems and not on any anticoagulation was seen in the urology clinic with persistent hematospermia for the last few years. A thorough history and examination including a digital examination of the prostate was unremarkable. Bleeding from his female partner was also ruled out. Investigations such as prostate specific antigen (PSA) blood test, urine culture, semen culture, and flexible cystoscopy were performed, and these investigations were also within normal limits. Due to his persistent hematospermia even after masturbation, a magnetic resonance imaging (MRI) of his pelvis was performed to rule out any sinister intrapelvic pathology. His MRI pelvis revealed a right seminal vesicle haemorrhage which was the cause of his hematospermia. He was treated conservatively with the advice to abstain from ejaculation for a few months. More importantly, we have also reassured the patient.

"Fungating" tumour? No, it's bacterial!

A fit and healthy 26-year-old woman presented to the general surgical team with epigastric pain and weight loss of 2 stones over 6 months. She has also a positive family history of ulcerative colitis. As her oesophagogastroduodenoscopy and colonoscopy were normal, a contrasted CT was requested, and it detected an inflammatory mass with fat streaking around her transverse colon. An intrauterine contraceptive device (IUCD) was noted. In light of the CT findings, she underwent a diagnostic laparoscopy. As the inflammatory mass was not separable from the transverse colon, a segmental transverse colectomy was proceeded. The histology revealed multiple actinomycosis abscesses in the mesentery. Subsequently, we learnt that her IUCD had been in situ for the last 7 years, and the source of actinomycosis abscesses is likely from her IUCD. The patient was recommended to have the coil removed and commenced on a 6 months course of amoxicillin.

Buried coin in the gastric mucosa.

A 29-year-old man presented to the Accident and Emergency department with abdominal cramping following ingestion of a 50 p coin 2½ weeks prior to presentation. He had not observed it pass in his stools. An abdominal radiograph confirmed the presence of the 50 p coin in his stomach. Subsequently, he had an oesophagogastroduodenoscopy (OGD) performed with a failure to visualise the coin. 1½ weeks later, he returned to the department as he was still unable to observe its passing in his stools. A repeated abdominal radiograph and a CT of the abdomen and pelvis revealed that the coin was still in his stomach. A second OGD was performed once again with a failure to visualise the coin. It appeared that the coin had migrated into his gastric mucosa.

Matrix Stone Occupying an Entire Renal Collecting System: A Case Report and Video of Diagnostic Ureterorenoscopy.

Renal matrix stones are a rare phenomenon and they present a diagnostic challenge due to their atypical radiological appearances in comparison to more commonly encountered renal tract calculi. We describe a case of known stone former presenting with loin pain and recurrent urinary tract infections who was diagnosed with a matrix stone. The video of the diagnostic flexiureterorenoscopy demonstrating the matrix stone occupying almost the entire right renal collecting system is also presented.

A rare presentation of haematuria: hip prosthesis in the bladder.

An 80-year-old woman presented to our department with visible haematuria and stage II acute kidney injury (AKI). She had stage IIB cervical cancer, for which she received chemotherapy and external beam radiotherapy in 2003. Four years later, she had a left dynamic hip screw for an extracapsular neck of femur fracture following a fall. In 2010, she underwent a right total hip replacement owing to osteoarthritis, and it was subsequently revised in 2012 owing to a right acetabular component failure. In this admission, her AKI improved with intravenous fluid administration and her haematuria settled following catheterisation with a three-way catheter and bladder irrigation with saline. She underwent a flexible cystoscopy which revealed that a part of her right hip prosthesis was in the bladder, having eroded through the right bony pelvis. However, she declined any surgical interventions.

Limberg flap in management of pilonidal sinus disease: systematic review and a local experience.

OBJECTIVES: To review published evidence of Limberg flap (LF) use in pilonidal sinus disease (PSD). We also included our local experience of LF. METHODS: Medline and Embase database were searched for the words 'pilonidal, sinus, Limberg, flap'. Non-English articles and those not-related to our scope of search were omitted. We included a retrospective study of patients underwent LF in our district hospital. Data including length of hospital stay, post-operative complications and recurrence were collected. RESULTS: Literature review revealed 68 studies (22 case series, 35 comparative studies, nine RCTs and two meta-analyses). Recurrence rate was 0-7.4% in case series. Recurrence rate in comparative studies was 0-8.3%, compared to 4-37.7% for primary closure and 0-11% for Karydakis flap. RCTs showed that LF or its modification is superior to primary closure, with comparable results to Karydakis flap. About 26 patients included in the cohort study (16 male, average age 27 years). Six patients presented with recurrent disease. Post-operative length of hospital stay was four to seven days. Post-operative complication rate was 11.5% - [two partial wound dehiscence, one wound infection]. Recurrence rate was 7.7%. Average follow-up was 18 months. CONCLUSIONS: Limberg flap presents a safe and effective method that can be offered for patients with primary or recurrent PSD.

Prostatic abscess: a rare complication of staghorn calculi.

A staghorn calculus is a calculus accommodating the majority of a renal calyx extending into the renal pelvis. A conservative approach to its treatment may lead to high morbidity and mortality rates. Such morbidity usually manifests with renal failure, obstructed upper urinary tractand/or life-threatening sepsis. Prostatic abscesses have never been associated with staghorn calculi in the literature. We report a case of a 70-year-old man who presented with sepsis, which was found to originate from a complex prostatic abscess. The patient had no history of urinary tract infections or risk factors. The authors believe that the incidentally identified staghorn calculi promoted the growth of Proteus mirabilis which led to the development of the prostatic abscess. The patient underwent a transurethral resection and drainage of the abscess following a failed course of antibiotic therapy. This case also highlights the paucity of guidelines available in treating prostatic abscesses.

Which Is Better? "Live" Surgical Broadcasts vs "As-Live" Surgical Broadcasts.

INTRODUCTION: Recently, the role of "live" surgical broadcasts (LSB) as an educational tool to demonstrate surgical techniques at conferences has been challenged, with concerns surrounding the well-being and safety of the patient as well as the surgeon. There have been notions that "as-live" surgical broadcasts (ALSB), prerecorded unedited videos showing either the whole procedure or key features, may be educationally superior. Our study was hence conducted to determine which was deemed better by a diverse group of international urologists. METHODS: All participants of the World Congress of Endourology held in October 2015 in London were invited to complete an electronic survey using the conference app regarding LSB demonstrations compared with ASLB, before the congress and again after the congress. Only ALSB videos were used in the congress. RESULTS: Both pre- and postconference surveys showed that 76.9% and 78.2% of the participants, respectively, perceived that more teaching could be achieved in less time using ASLB. 52.8% and 60.3% of respondents indicated ALSB as being superior to LSB before and after the conference, respectively. Furthermore, 52.8% and 54.5% of respondents regarded ALSB videos as having more educational value than LSB before and after the conference, respectively. CONCLUSION: There was little perceived difference between ALSB and LSB, showing that ALSB are at least noninferior as an educational tool. In view of the numerous ethical and logistical issues with LSB, we would advocate ASLB as the educational tool of choice for future surgical demonstration at conferences.

Prevascular femoral hernia and its relation with inferior epigastric vessels: a rare presentation of the femoral hernia sac.

A 61-year-old man presented to the emergency department, with a 2-week history of a painful lump on his right groin. A diagnosis of an irreducible right femoral hernia was made. As such, an urgent operation was carried out on the same day, and the patient was found to have a rare prevascular femoral hernia in which the sac was lying over the femoral vessels and split by the inferior epigastric vessels into 2 components resembling 2 trouser limbs. The hernia sac presented in a different and challenging way that necessitated meticulous dissection and full orientation of the anatomy of the femoral triangle. Complete dissection and control of the inferior epigastric vessels, and complete reduction of the sac followed by repair with a prosthetic mesh plug were performed successfully. The patient was discharged home the next day.

Primary breast lymphoma presenting as non-healing axillary abscess.

A 67-year-old woman with non-insulin dependent diabetes mellitus with a history consistent with a right axillary abscess, presented to her general practitioner (GP). A diagnosis of folliculitis was made and the GP started a course of flucloxacillin. Despite antibiotics, the patient's symptoms worsened and the abscess increased in size. This prompted her GP to perform an incision and drainage procedure of the abscess. The practice nurse subsequently oversaw the follow-up care of the wound. Two months after the incision and drainage, and after regular wound dressing, the patient was referred to the acute surgical team with a complicated, non-healing right axillary abscess cavity and associated generalised right breast cellulitis. There was no history of breast symptoms prior to the onset of the axillary abscess. The patient underwent wound debridement, washout and application of negative pressure vacuum therapy. Biopsies revealed primary breast lymphoma (B-cell). She underwent radical chemotherapy and is currently in remission.
