[Pelvic Reconstruction in Abdominal Trachelectomy and Bilateral Salpingo-Oophorectomy for Occult Uterine Endometrial Cancer Found in Specimens Removed in the Context of Laparoscopic Sacrocolpopexy].

In the patients undergoing pelvic organ prolapse (POP) repairs, the incidence of occult uterine endometrial cancer is low and there is no established management procedure for preoperative cancer screening. We report a case of pelvic reconstruction in abdominal trachelectomy and bilateral salpingo-oophorectomy for occult uterine endometrial cancer found in specimens removed in the context of laparoscopic sacrocolpopexy (LSC). A 70-year-old woman presented to our center with cystocele. She underwent LSC and laparoscopic supracervical hysterectomy. She had no atypical genital bleeding; and, transvaginal ultrasound, pelvic plane magnetic resonance imaging and cervical cytology showed no evidence of malignancy. However, the pathological examination showed uterine endometrial cancer. She underwent trachelectomy, bilateral salpingo-oophorectomy and pelvic lymph node dissection. A part of mesh was removed with a cervical stamp, but the remaining mesh was sewn together. At 5 months after the operation, no recurrence of uterine endometrial cancer and POP was seen.

Medium term anatomical and functional outcomes following modified laparoscopic sacrocolpopexy.

INTRODUCTION AND HYPOTHESIS: We evaluated the anatomical and functional outcomes following modified laparoscopic sacrocolpopexy (LSC) utilizing deep dissection of the vaginal walls and distal mesh fixation at the anterior and posterior compartments. We hypothesized that anatomical and functional outcomes improve after this modified LSC technique. METHODS: This was a retrospective study of all women (n = 240) who underwent LSC for pelvic organ prolapse (POP) from January to December 2017 in a tertiary center. POP-Q staging, validated questionnaires (International Consultation on Incontinence Questionnaire-Short Form [ICIQ-SF] and Pelvic Floor Distress Inventory Questionnaire-Short Form), and uroflowmetry were used to evaluate the anatomical and functional outcomes. Statistical analyses were performed using McNemar test and repeated measures analysis of variance with Fisher's least significant difference post hoc (p < 0.05). RESULTS: The anatomical success rate is 96%, with a prolapse recurrence rate of 3.8% at 3-year follow-up. Bulge symptoms and anatomical compartments were significantly improved after LSC. Clinically, there were significant improvements after LSC in voiding dysfunction and bowel symptoms. Also, there was a significant increase in stress urinary incontinence and non-significant decrease in mixed urinary incontinence and urge urinary incontinence. ICIQ-SF and Colorectal-Anal Distress Inventory 8 scores were significantly lower after LSC, signifying improvement in incontinence and bowel symptoms. CONCLUSION: Our modified LSC technique is safe and effective in restoring level 1 and level 2 supports, without adverse effects on urinary and bowel function. Bladder and bowel symptoms have also been found to keep improving over time.

Predictive urodynamic factors for de novo stress urinary incontinence after laparoscopic sacrocolpopexy for pelvic organ prolapse.

OBJECTIVES: Laparoscopic sacrocolpopexy is often performed to treat pelvic organ prolapse. Preoperative stress urinary incontinence (SUI) can improve after laparoscopic sacrocolpopexy. In contrast, some patients without incontinence preoperatively develop SUI after pelvic organ prolapse repair (ie, de novo SUI). This study aimed to identify the preoperative predictive factors of de novo SUI after laparoscopic sacrocolpopexy. METHODS: A total of 858 patients underwent laparoscopic sacrocolpopexy between January 2013 and November 2017 at Kameda Medical Center. Urodynamic studies were performed pre- and postoperatively on 75 patients. This retrospective study included 43 of 75 patients who did not have SUI preoperatively. We assessed urethral function according to functional profile length and maximum urethral closure pressure. We evaluated voiding function in terms of maximum flow rate, detrusor pressure at maximum flow rate, and postvoid residual volume. Furthermore, each factor was compared between de novo SUI-positive and SUI-negative groups. RESULTS: After laparoscopic sacrocolpopexy, 30 (69.8%) patients presented with SUI. The preoperative maximum urethral closure pressure was significantly lower in the de novo SUI-positive group (36.0 cmH2 O) than in the de novo SUI-negative group (50.5 cmH2 O, P = .020). More patients with maximum urethral closure pressure <40 cmH2 O had de novo SUI than patients with maximum urethral closure pressure ≥40 cmH2 O (P = .004). There were no significant differences between preoperative maximum urethral closure pressure and postoperative maximum urethral closure pressure in either group. CONCLUSIONS: Low preoperative maximum urethral closure pressure, particularly maximum urethral closure pressure <40 cmH2 O, is a predictor of de novo SUI after laparoscopic sacrocolpopexy.

Laparoscopic repair of vesicovaginal fistula caused by radiation therapy: Use of a perirectal fat interposition graft.

INTRODUCTION: We present a case of laparoscopic repair of vesicovaginal fistula caused by radiation therapy using a perirectal fatty tissue interposition graft. CASE PRESENTATION: A 72-year-old woman was diagnosed with vesicovaginal fistula induced by radiation therapy. Repair of the vesicovaginal fistula was achieved via laparoscopic approach. The fistula was exposed, followed by excision of fistula tract, fine dissection to achieve a traction-free approximation of bladder mucosa, then water-tight closure. An interposition graft derived from the perirectal fat was inserted to reduce the risk of repair failure. The patient did not have the incontinence problem at 1-year follow-up. CONCLUSION: The laparoscopic approach for vesicovaginal fistula repair is minimally invasiveness. Preparation of the interposition graft derived from the perirectal fatty tissue was easy and its mobility to achieve closure of the fistula was acceptable. Thus, this procedure is feasible for the repair of poorly vascularized tissues such as radiation-induced fistulas.

Laparoscopic sacrocolpopexy in a patient with vault prolapse of the sigmoid stump after vaginoplasty in Mayer-Rokitansky-Küster-Hauser syndrome: A case report.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare congenital anomaly that results in Müllerian agenesis that affects the uterus and upper two-thirds of the vagina. Sigmoid vaginoplasty is a surgical treatment option; however, vaginal prolapse may result as a complication of the sigmoid neovagina. There are no standards for treatment due to the rarity of this condition. We present the case of a 59-year-old woman with a history of sigmoid vaginoplasty who underwent laparoscopic sacrocolpopexy (LSC) for grade IV sigmoid stump prolapse. The patient had a successful outcome and no evidence of recurrent prolapse. This clinical case reveals the feasibility of LSC as a surgical treatment for sigmoid stump prolapses in patients with MRKH syndrome.

Clinical outcomes after laparoscopic sacrocolpopexy for pelvic organ prolapse: A 3-year follow-up study.

OBJECTIVES: To evaluate the mid-range subjective and objective success rate of laparoscopic sacrocolpopexy. METHODS: Of the 317 women with pelvic organ prolapse who underwent laparoscopic sacrocolpopexy surgery at the same center between January 2013 and March 2015, we assessed 233 patients who were followed up for >3 years. We carried out urogynecological examinations and used questionnaires for the postoperative assessment of the patients. Scoring 0 points on question 3 of the Pelvic Floor Distress Inventory-20 was considered to show subjective success. Objective success was defined as stage 0 or 1 on the Pelvic Organ Prolapse Quantification. RESULTS: The subjective and objective success rates in the third year after surgery were 89.7% (209/233) and 90.6% (211/233), respectively, and those in the first year were 90.6% (211/233) and 91.0% (212/233), respectively. Perioperative complications included bladder injury (0.4%) in one case and vaginal wall injury (0.4%) in one case. Postoperative complications included the incidence of chronic pain (mesh retraction) in one case, which was the only case requiring re-operation due to complications (0.4%); vaginal suture exposure (0.4%) in one case; port-site hernia (0.4%) in one case; and subileus (0.4%) in one case. The complications associated with voiding function included de novo stress urinary incontinence (20.6%) in 48 cases, out of which there were 12 cases of de novo overactive bladder (5.2%) and eight cases required midurethral sling procedures. CONCLUSIONS: Laparoscopic sacrocolpopexy provides a good outcome with a low rate of subjective and objective recurrence and surgical complications.

Lower urinary tract function improves after laparoscopic sacrocolpopexy for elderly patients with pelvic organ prolapse.

OBJECTIVES: Pelvic organ prolapse (POP) is relatively common in the elderly population. Laparoscopic sacrocolpopexy (LSC) has been reported by several studies to be a less invasive treatment option as compared to open sacrocolpopexy. However, almost all prior reports focused on the complications or surgical obstacles. The present study was designed to examine POP patients of all ages and assess lower urinary tract function before and after LSC. METHODS: This retrospective study examined the results of LSC performed in POP patients. Urodynamic studies were performed pre- and postoperatively in 50 patients, with the subjects divided into two groups containing those less than and those older than 65 years of age. We performed a pressure flow study. We examined bladder functions by evaluating bladder capacity, detrusor pressure at maximum flow (PdetQmax), maximum flow rate (Qmax), normal desire to void, strong desire to void, voided volume, and postvoid residual volume (PVR). Statistical analysis was performed using Wilcoxon signed rank test. Values of P < .05 were considered significant. RESULTS: With regard to the pressure-flow study parameters, there was a significant increase in the normal desire to void and bladder capacity only in the ≥65 age group. After the operation, there was a significant increase in the mean postoperative Qmax and voided volume, while there was a significant decrease in the PdetQmax and PVR as compared to the preoperative values only in the ≥65 age group. CONCLUSIONS: Results show that in elderly patients with POP, LSC might be a valid option with regard to potentially regaining urinary tract function.

Transvaginal surgery using self-cut mesh for pelvic organ prolapse: 3-year clinical outcomes.

OBJECTIVES: To evaluate subjective and objective outcomes, complication, recurrence, and reoperation rates after transvaginal mesh surgery for the management of pelvic organ prolapse. METHODS: This was a retrospective analysis of transvaginal mesh surgery carried out using self-cut mesh measuring subjective outcomes using validated questionnaires, and objective outcomes using Pelvic Organ Prolapse Quantification. Patients diagnosed with stage ≥2 pelvic organ prolapse were counseled about all possible surgical options. After thorough explanation about the benefits and risks during transvaginal mesh surgery, patients who gave signed consent were scheduled for surgery and evaluated at 1 and 3 years postoperatively. RESULTS: We included 101 patients who completed a minimum of 3-year follow up. One year and 3-year follow up showed significant improvement both on subjective and objective outcomes. Recurrences were observed in three patients (3%), with one (1%) patient undergoing reoperation. One case (1%) of intraoperative complication (bladder injury) and four cases (4%) of postoperative complications (two mesh exposure, one hematoma and one significant increase in post-voiding residual) were recorded. Overall patients' satisfaction was positive. CONCLUSIONS: Transvaginal mesh surgery using self-cut mesh is associated with significant improvement in both subjective and objective outcomes, offering low recurrence and complication rates, and high patient satisfaction rates. It can be a safe, effective and cost-efficient option not only for recurrence cases, but also as primary management of pelvic organ prolapse using a standardized technique and proper patient selection.

Laparoscopic lateral suspension for pelvic organ prolapse in a case with difficulty in performing laparoscopic sacrocolpopexy.

INTRODUCTION: Mesh fixation at the promontory is the most important procedure in laparoscopic sacrocolpopexy. We present a case of pelvic organ prolapse wherein sacrocolpopexy was converted to lateral suspension intraoperatively due to tissue weakness of the promontory. CASE PRESENTATION: A 66-year-old woman with a sensation of bulge in the vagina presented to our clinic. She was diagnosed with uterine prolapse (grade III). Laparoscopic sacrocolpopexy was planned; exposure of the promontory and mesh fixation at the vesicovaginal and rectovaginal space could be smoothly performed. However, handling the needle at the promontory was impossible due to tissue weakness of the anterior longitudinal ligament of the sacrum. Consequently, mesh fixation was converted to lateral suspension. CONCLUSION: Difficult mesh fixation at the promontory is not rare in laparoscopic sacrocolpopexy. Lateral suspension may be useful as a trouble-shooting procedure for laparoscopic sacrocolpopexy, and surgeons performing laparoscopic sacrocolpopexy should know this procedure.

Clinical and urodynamic assessment in patients with pelvic organ prolapse before and after laparoscopic sacrocolpopexy.

INTRODUCTION AND HYPOTHESIS: We hypothesized that patient-reported urinary symptoms and urodynamic evaluation improve after laparoscopic sacrocolpopexy (LSC) despite deeper vesicovaginal space dissection. METHODS: This was a retrospective study of women with pelvic organ prolapse who underwent LSC from January 2013 to January 2016 in a tertiary center. Urinary function was clinically evaluated using the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), the Overactive Bladder Symptom Score (OABSS) and the Pelvic Floor Distress Inventory Questionnaire- - Short Form 20 (PFDI-20). Urodynamic assessment was performed before and 6 months after surgery. The Wilcoxon signed-ranks test and the McNemar test were applied with p < 0.05 considered significant. RESULTS: A total of 155 patients were included in the study. Of these, 46 had urodynamic assessment before and after LSC. There were significant improvements after LSC in urodynamic storage phase parameters (higher volume at first desire, higher volume at strong desire, and larger bladder capacity) and voiding phase parameters (higher Q max, higher Q ave, lower P det Q max, increased voided volume and reduced postvoid residual urine volume). Clinically, there was a significant increase after LSC in stress urinary incontinence and a significant reduction in urgency urinary incontinence, overactive bladder and voiding dysfunction. CONCLUSIONS: Apart from increased stress urinary incontinence, there was an improvement in overall urinary function in terms of patient-reported symptoms and urodynamics, despite deep vesicovaginal space dissection. Hence, LSC is a viable surgical option for pelvic organ prolapse, restoring both level 1 and level 2 support without detrimental effects on urinary function.

[CLINICAL OUTCOMES OF LAPAROSCOPIC SACROCOLPOPEXY FOR PELVIC ORGAN PROLAPSE: A RETROSPECTIVE ANALYSIS OF 500 CASES FROM A SINGLE INSTITUTION].

(Objectives) Laparoscopic sacrocolpopexy (LSC) is becoming a more popular alternative for pelvic organ prolapse (POP) repair in Japan in the recent years. This study aimed to evaluate the safety and efficacy of LSC. (Patients and methods) This is a retrospective study on all the LSC cases that were performed in Urogynecology center, Kameda Medical Center, Japan from January 2013 to March 2016. Medical records of all the patients were retrieved and details on operating time, estimated blood loss, perioperative complications, anatomical recurrence (postoperative POP-Q stage≥II) rate and reoperation rate were assessed.Our procedure of LSC used two pieces of polypropylene mesh placed on the vesico-vaginal and recto-vaginal space in which the dissection was extended to the level of the bladder neck and levator ani muscle. Subtotal hysterectomy was performed in almost all patients with uterus except in 39 women who chose to preserve their uterus. Additionally, multivariate analysis of risk factors for recurrence-free survival was performed using the Cox regression method. (Results) Five hundred and five patients who were diagnosed as POP (cystocele, rectocele, enterocele, uterine prolapse, vaginal vault prolapse) were included. The mean operating time and estimated blood loss were 236 min and 27.2 ml. There were 2.6% perioperative complication rate and 1.0% severe complication rate (Clavien grade≥IIIa). With a median follow-up of 12 months, anatomical recurrence rate was 8.0%, significant anatomical recurrence (stage≥III) rate was 1.2% and reoperation rate was 1.0%. Preoperative POP-Q stage IV was found as independent risk factors for anatomical recurrence. (Conclusions) The present study demonstrated a relatively low complication rate, low significant anatomical recurrence rate and low reoperation rate. Therefore, LSC is a safe and effective surgical treatment for various types of POP.

Autoimmune hemolytic anemia associated with renal urothelial cancer: A case report and literature review.

BACKGROUND: Autoimmune hemolytic anemia (AIHA) is hemolytic anemia characterized by autoantibodies directed against red blood cells. AIHA can be induced by hematological neoplasms such as malignant lymphoma, but is rarely observed in the urological field. We report a case of renal urothelial cancer inducing Coombs-positive warm AIHA and severe thrombocytopenia that was responsive to nephroureterectomy. CASE PRESENTATION: A 52-year-old man presented with a 1-month history of general weakness and dizziness. Hemoglobin level was 4.2 g/dL, and direct and indirect Coombs tests both yielded positive results. Abdominal computed tomography revealed huge left hydronephrosis due to a renal pelvic tumor measuring 4.0 x 4.0 x 3.0 cm, and renal regional lymph-node involvement was also observed and suspected as metastasis. Corticosteroid therapy was administered, and nephroureterectomy was performed. After surgical resection, the hemoglobin level gradually normalized, and direct and indirect Coombs tests yielded negative results. We thus diagnosed warm AIHA associated with renal urothelial cancer. CONCLUSION: To the best of our knowledge, this represents the first report of AIHA associated with renal urothelial cancer and severe thrombocytopenia responsive to nephroureterectomy. Renal urothelial cancer needs to be included in the differential diagnoses for warm AIHA, and nephroureterectomy represents a treatment option for AIHA.

The relationship between renal volume and renal function in autosomal dominant polycystic kidney disease.

BACKGROUND: In patients with autosomal dominant polycystic kidney disease (ADPKD), renal cysts grow exponentially. Since remaining renal parenchyma has a capacity to compensate for the loss of glomerular filtration, the glomerular filtration rate (GFR) may be sustained until the disease progresses. The purpose of this study was to determine if renal volumetric indices and clinical parameters are associated with renal function in Japanese patients with ADPKD. METHODS: In 73 ADPKD patients (28 men, 45 women), the associations of mean systolic blood pressure, mean diastolic blood pressure, estimated GFR (eGFR), the amount of proteinuria and albuminuria, body mass index (BMI), brachial-ankle pulse wave velocity (baPWV), ankle-brachial index, and total kidney volume (TKV) were retrospectively analyzed. RESULTS: Multivariate linear regression analysis showed that eGFR was significantly and independently inversely correlated with patients' age and BMI. The median change in eGFR per year (ΔeGFR/y) was -2.8 ml/min/1.73 m(2)/year. Multiple linear regression analysis showed that ΔeGFR/y was significantly and independently inversely correlated with the change in TKV per year (ΔTKV/y). Multiple linear regression analysis showed that ΔTKV/y was significantly related to initial TKV and the change in albuminuria per year. CONCLUSIONS: This study demonstrated a significant relationship between the change in renal function and the change in renal volume in Japanese ADPKD patients without renal insufficiency. It is possible that the volume measurements can be used as useful markers for disease progression in Japanese ADPKD patients.

Combined inhibitory effects of soy isoflavones and curcumin on the production of prostate-specific antigen.

BACKGROUND: Sustained chronic inflammation in the prostate promotes prostate carcinogenesis. Since an elevated level of prostate-specific antigen (PSA) per se reflects the presence of inflammation in the prostate, intervention to improve the PSA value might potentially have beneficial effects for the prevention of the development of prostate cancer. Isoflavones and curcumin have anti-inflammatory and anti-oxidant properties. We examined the biological effects of soy isoflavones and curcumin on LNCaP cells. After that, we conducted a clinical trial for men who received prostate biopsies, but were not found to have prostate cancer, to evaluate the effects of soy isoflavones and curcumin on serum PSA levels. METHODS: The expression of androgen receptor and PSA were examined in LNCaP cells before and after treatment of isoflavones and/or curcumin. Eighty-five participants were randomized to take a supplement containing isoflavones and curcumin or placebo daily in a double-blind study. Subjects were subdivided by the cut-off of their baseline PSA value at 10 microg/ml. We evaluated values of PSA before and 6 months after treatment. RESULTS: The production of PSA were markedly decreased by the combined treatment of isoflavones and curcumin in prostate cancer cell line, LNCaP. The expression of the androgen receptor was also suppressed by the treatment. In clinical trials, PSA levels decreased in the patients group with PSA >or= 10 treated with supplement containing isoflavones and curcumin (P = 0.01). CONCLUSIONS: Our results indicated that isoflavones and curcumin could modulate serum PSA levels. Curcumin presumably synergizes with isoflavones to suppress PSA production in prostate cells through the anti-androgen effects.

Novel germ line mutation p53-P177R in adult adrenocortical carcinoma producing neuron-specific enolase as a possible marker.

Adrenocortical cancer (ACC) is a rare and aggressive endocrine tumor. The patient presented with a large retroperitoneum tumor and lung metastases. Removal of the adrenocortical tumor with part of the transverse colon and tail of the pancreas, spleen and kidney was successfully performed following chemotherapy. Levels of serum neuron-specific enolase (NSE) were found to be markedly high before surgery and may be clinically useful markers for monitoring tumor status during management. Immunohistochemical studies showed that the cancer cells were positive for NSE and overexpression of p53. We identified a novel germ line variant of the 177 mutant (Pro to Arg; P177R) of p53 by genomic sequencing. The genetic and biochemical data presented in this case confirm the importance of screening for p53 status in ACC with inherited cancer syndrome.

Real-time MRI of orthotopic ileal neobladder voiding: preliminary findings.

OBJECTIVES: The purpose of this preliminary study was to analyze the dynamic changes in the configuration of the neobladder and naïve bladder during voiding using real-time MRI. METHODS: This study included 10 male patients who had a radical cystectomy and an ileal orthotopic neobladder due to organ-confined bladder cancer and had good urinary function, and 5 male control volunteers. With the subjects in the lateral decubitus position, real-time MRI was performed during micturition. A sagittal slice orientation was used to depict the bladder and the entire length of the urethra; individual movements along the X-axis and Y-axis of the bottom and top of the neobladder and the naïve bladder were recorded and analyzed. Urodynamic studies (UDS) and video voiding cystourethrography were performed in patients. RESULTS: Five of the 10 neobladder patients could void in the lateral decubitus position. In normal controls and patients who could void, the bladder outlet bladder moved ventrocranially during micturition. The ileal bladder outlet moved a significantly longer distance than the naïve bladder during micturition (X-axis, -13.4+/-1.5 vs. -3.6+/-4.3 cm, p=0.0014; Y-axis, -10.6+/-0.5 vs. -2.0+/-6.5 cm, p=0.0187). The distance that the bladder top moved between the naïve bladders and the neobladder did not differ. UDS did not show a difference between patients who could and could not void at lateral position. CONCLUSIONS: During micturition, the neobladder was found to rotate and move more dynamically than the naïve bladder. Real-time MRI is useful for assessing dynamic voiding function of orthotopic neobladders.

[A case of a giant adrenal myelolipoma in a man with spinal cord injury].

A 38-year-old man in a wheelchair for spinal cord injury from a traffic accident was referred to our hospital with complaint of dull right flank pain. The patient had a history of skin ulcer formation on both toes due to poor circulation. Abdominal ultrasonography and computed tomographic scan revealed a huge retroperitoneal tumor compressing the right kidney. Serum levels of cortisol, adrenocorticotropic hormone, aldosterone, adrenalin, noradrenalin, urinary levels of vanillylmandelic acid, homovanillic acid, 17-ketosteroid and 17-hydroxycorticosteroid were all within normal limits. Combining all preoperative diagnostic information, the possibility of retroperitoneal liposarcoma could not be thoroughly ruled out. The patient consented to undergo resection of the tumor with the right kidney. Prior to the scheduled operation simulation of the positioning on the operation table was done to evaluate the compressing pressure. During operation decompressing pads were used to minimize the compressing pressure and intermittent pneumatic compression was also used to prevent pressure ulcer and facilitate circulation to the lower extremities. Five thousands units of heparin (FragminR, Pfizer, USA) was used daily to prevent deep vein thrombosis until the patient could use his wheelchair. Perioperative rehabilitation was conducted by a team of physical therapists. The excised tumor weighed 1,320 g. Pathologic diagnosis was an adrenal myelolipoma. Convalescence was uneventful and the patient was discharged on the 10th post operative day. Between 1992 and 2006, 80 cases of adrenal myelolipoma were reported in Japan. Our case was found to be the second largest one. We reviewed these 80 cases and discussed the diagnosis and treatment strategy of the adrenal myelolipoma. We also discussed the perioperative management for patients with spinal cord injury.
