The nutcracker syndrome: its role in the pelvic venous disorders.
(25/351)
BACKGROUND: Symptoms of pelvic venous congestion (chronic pelvic pain, dyspareunia, dysuria, and dysmenorrhea) have been attributed to massive gonadal reflux. However, obstruction of the gonadal outflow may produce similar symptoms. Mesoaortic compression of the left renal vein (nutcracker syndrome) produces both obstruction and reflux, resulting in symptoms of pelvic congestion. We describe the diagnosis and management of nine patients studied in our institutions. MATERIALS AND METHODS: From a group of 51 female patients with pelvic congestion symptoms studied at our institutions, there were nine patients with symptoms of pelvic congestion, microscopic hematuria, and left-sided flank pain. The diagnosis of the nutcracker syndrome was suspected based on clinical examination, Doppler scan, duplex ultrasound scan, computed tomography scan, and magnetic resonance imaging. The diagnosis was confirmed by retrograde cine-video-angiography with renocaval gradient determination and catheterization of both internal iliac venous systems. All patients had a renocaval pressure gradient >4 mm Hg (normal, 0-1 mm Hg). Renal compression was relieved by external stent (ES) in two patients, internal stent (IS) in one patient, and gonadocaval bypass (GCB) in three. GCB was preceded by coil embolization of internal iliac vein tributaries connecting with lower-extremity varicose veins in three patients. Three patients deferred surgery and are under observation. Mean follow-up time was 36 months (range, 12-72 months). RESULTS: Hematuria disappeared postoperatively in all patients. ES and IS normalized the renocaval gradient and resulted in significant alleviation of symptoms (90% improvement on a scale of 0-10 where 0 = no improvement and 10 = greatest improvement). Two patients with GCB had a residual gradient of 3 mm Hg. The third patient normalized the gradient. In this group, improvement of symptoms was 60%. Patients awaiting surgery are being treated conservatively (elastic stockings, hormones, and pelvic compression). They have shown only moderate improvement. CONCLUSION: The nutcracker syndrome should be considered in women with symptoms of pelvic venous congestion and hematuria. The diagnosis is suspected by compression of the left renal vein on magnetic resonance imaging or computed tomography scan and confirmed by retrograde cine-video-angiography with determination of the renocaval gradient. Internal and external renal stenting as well as gonadocaval bypass are effective methods of treatment of the nutcracker syndrome. IS and ES were accompanied by better results than GCB. Surgical and radiologic interventional methods should be guided by the clinical, radiologic, and hemodynamic findings. (+info)
Relationship between stage, site and morphological characteristics of pelvic endometriosis and pain.
(26/351)
BACKGROUND: The relationship between frequency and severity of pain symptoms and site, stage and morphological characteristics of endometriotic lesions was analysed in a multicentre cross-sectional observational study. METHODS: A total of 469 women (median age 31 years, range 18-45) who met the following criteria were consecutively observed in the participating centres during the study period: age 18-45 years, first laparoscopic or laparotomic diagnosis of endometriosis, pain symptoms lasting > or = 6 months, pain as the main or only complaint of the condition, absence of pelvic anomalies and no previous pelvic surgery. Dysmenorrhoea and non-menstrual pain were evaluated using a multidimensional verbal rating scale. The women were requested to grade the severity of dysmenorrhoea, non-menstrual pelvic pain and deep dyspareunia using a 10-point linear analogue scale. RESULTS: Dysmenorrhoea was present in 77% of subjects with ovarian endometriosis, 88% of those with endometriosis of the peritoneum, 92% of subjects with endometriosis of both ovary and peritoneum and in all the subjects with endometriosis of rectovaginal septum. These differences were not statistically significant after Bonferroni's correction. No marked difference emerged between the severity of dysmenorrhoea and site of endometriosis, but women with ovarian endometriosis tended to have lower scores (not significant). No clear association emerged between frequency and severity of non-menstrual pain, dyspareunia and site of endometriosis and the presence and severity of dysmenorrhoea, non-menstrual pain and dyspareunia. Dyspareunia was more frequently reported in women with only atypical endometriosis (56.8%) versus 47.7% in women with typical endometriosis, but with borderline significance (P = 0.05). Dyspareunia occurred in 68.2% of patients with both typical and atypical lesions. CONCLUSIONS: The results of this study find no clear-cut association between stage, site or morphological characteristics of pelvic endometriosis and pain. (+info)
Transvaginal colour Doppler in patients with ovarian endometriomas and pelvic pain.
(27/351)
BACKGROUND: The aim of this investigation was to correlate ovarian endometrioma vascularization with the presence of pelvic pain. METHODS: The presence of blood flow, peak systolic velocity (PSV, cm/s) and lowest pulsatility index (PI), assessed by transvaginal colour Doppler ultrasonography and CA-125 plasma concentrations, were retrospectively analysed in 74 patients who had undergone operations for cystic ovarian endometriosis. Fifty-two patients were asymptomatic (group A) and 22 presented with pelvic pain (group B). There were 56 endometriomas in group A and 26 in group B. RESULTS: Blood flow was found in 66.1 and 88.5% of endometriomas in groups A and B respectively (P = 0.036). PI was significantly lower (P = 0.009) and CA-125 concentration higher (P = 0.0004) in group B. There were no differences in PSV. CONCLUSIONS: We conclude that vascularization of ovarian endometriomas in patients presenting with pelvic pain is higher than in asymptomatic patients. This could be an indicator of endometriosis activity. (+info)
Clinical implications of postsurgical adhesions.
(28/351)
Adhesion development can have a major impact on a patient's subsequent health. Adhesions are a significant source of impaired organ functioning, decreased fertility, bowel obstruction, difficult re-operation, and possibly pain. Consequently, their financial sequelae are also extraordinary, with more than one billion dollars spent in the USA in 1994 on the bowel obstruction component alone. Performing adhesiolysis for pain relief appears efficacious in certain subsets of women. Unfortunately even when lysed, adhesions have a great propensity to reform. Adhesions are prevalent in all surgical fields, and nearly any compartment of the body. For treatment of infertility and recurrent pregnancy loss, lysis of intrauterine adhesions results in improved fecundability and decreased pregnancy loss. (+info)
X Chromosomal short tandem repeat polymorphisms near the phosphoglycerate kinase gene in men with chronic prostatitis.
(29/351)
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) causes substantial morbidity afflicting approximately 10% of adult males. Treatment is often empirical and ineffective since the etiology is unknown. Other prostate and genitourinary diseases have genetic components suggesting that CP/CPPS may also be influenced by genetic predisposition. We recently reported a highly polymorphic short tandem repeat (STR) locus near the phosphoglycerate kinase gene within Xq11-13. Because this STR is in a region known to predispose towards other prostate diseases, we compared STR polymorphisms in 120 CP/CPPS patients and 300 control blood donors. Nine distinct allele sizes were detected, ranging from 8 to 15 repeats of the tetrameric STR plus a mutant allele (9.5) with a six base deletion in the flanking DNA sequence. The overall allele size distribution in the CP/CPPS patients differed from controls (Chi-square=19.252, df=8, P=0.0231). Frequencies of two specific alleles, 9.5 and 15, differed significantly in CP/CPPS vs. control subjects and allele 10 differed with marginal significance. Alleles 9.5 and 10 were both more common in CP/CPPS patients than controls while allele 15 was less common. These observations suggest that Xq11-13 may contain one or more genetic loci that predispose toward CP/CPPS. Further investigations involving family studies, larger patient populations, and other control groups may help elucidate this potential genetic predisposition in CP/CPPS. (+info)
Microlaparoscopic conscious pain mapping in the evaluation of chronic pelvic pain: a case report.
(30/351)
Chronic pelvic pain is a debilitating, life-altering syndrome that negatively affects a woman's quality of life and personal relationships. Many women continue to suffer with pelvic pain despite having undergone multiple medical and surgical treatments. Unfortunately, some women are incorrectly labeled as having psychological illness when organic disease may be present. I report a case of a woman who underwent multiple pelvic and abdominal surgeries before the cause of her pain was identified through microlaparoscopic conscious pain mapping. (+info)
Autoimmune T cell responses to seminal plasma in chronic pelvic pain syndrome (CPPS).
(31/351)
The aetiology of chronic prostatitis is not understood. The aim of this study is to investigate an autoimmune hypothesis by looking for T cell proliferation in response to proteins of the seminal plasma. We studied peripheral blood mononuclear cell proliferation from 20 patients with chronic prostatitis and 20 aged-matched controls in response to serial dilutions of seminal plasma (SP) from themselves (autologous SP) and from a healthy individual without the disease (allo-SP). We found that the patients have a statistically greater lymphocyte proliferation to autologous SP at the 1/50 dilution on day 6 compared to controls (P = 0 x 01). They also have a greater proliferation to allo-SP on both day 5 (P = 0 x 001) and day 6 (P = 0 x 01) at the same dilution. Using a stimulation index (SI) of 9 to either autologous SP or allo-SP on day 6 at the 1/50 dilution as a definition of a proliferative response to SP, then 13/20 patients as compared to 3/20 controls showed a proliferative response to SP (P = 0 x 003, Fishers exact test). These data support an autoimmune hypothesis for chronic prostatitis. (+info)
Lumbar back and posterior pelvic pain during pregnancy: a 3-year follow-up.
(32/351)
This study is a prospective, consecutive, 3-year cohort study of women with back pain in an index pregnancy. The aim was to describe the physical status and disability among women with back pain 3 years after delivery. Pain was identified as lumbar back pain, posterior pelvic pain or combined lumbar as well as posterior pelvic pain. Previous studies have established that all three types of pain can be reduced by structured physiotherapy during pregnancy, and the beneficial effect may last for several years. Though it is known that some women have residual pain for a long time, the relative incidence of the three pain types and their degree of disability associated with each have never been reported. Neither has any study presented findings of a physical examination of women 3 years post partum with a focus on the type of pain. All women who were registered as having experienced back pain during an index pregnancy were interviewed by mail 3 years post partum. Women who had residual back pain filled in an additional questionnaire and were physically examined. Out of 799 pregnant women, 231 had some type of back pain during the index pregnancy, and 41 women had pain 3 years later. Women with combined lumbar and posterior pelvic pain were significantly more disabled ( P<0.05) and had significantly lower endurance in the lumbar back and hip abduction muscles ( P<0.01). Some 5% of all pregnant women, or 20% of all women with back pain during pregnancy, had pain 3 years later. The key problem may be poor muscle function in the back and pelvis. (+info)
